Start: 7
7 + 7 = 14
14 + 7 = 21
21 + 7 = 28
28 + 7 = 35
35 + 7 = 42
42 + 7 = 49
49 + 7 = 56
56 + 7 = 63
63 + 7 = 70
Multiples of 7 by Multiplication
We find the multiples of 7 by multiplying seven by the counting numbers. Hence, we will multiply 7 by 1, 7 by 2, 7 by 3, and so on. The table below shows the first ten multiples of 7 by multiplying 7 by the first ten counting numbers.
1 × 7 = 7 |

Multiples of 7 by Division
Numbers that can be divided by seven precisely without any remainder are said to be multiples of seven.
Let us have the following examples:
( a ) 56 ÷ 7 = 8; since 56 can be divided by 7 without a remainder, it is a multiple of 7.
( b ) 77 ÷ 7 = 11; since 77 can be divided by 7 without a remainder, it is a multiple of 7.
( c ) 98 ÷ 7 = 14; since 98 can be divided by 7 without a remainder, it is a multiple of 7.
( d ) 105 ÷ 7 = 15; since 15 can be divided by 7 without a remainder, it is a multiple of 7.
( e ) 175 ÷ 7 = 25; since 175 can be divided by 7 without a remainder, it is a multiple of 7.
Multiples of 7 by a Simple Trick
Checking a number if it is a multiple of 7 involves these easy steps.
Step 1: Find twice the last digit of the given number.
Step 2: Subtract the answer in step 1 from the remaining digits.
Step 3: The given number is a multiple of 7 if the result in Step 2 is a multiple of 7.
Let us have the following numbers and check if they are multiples of 7:
( a ) 238 ( b ) 623 ( c ) 889 ( d ) 925
Solution
( a ) 238
To check if 238 is a multiple of 7, we must get twice 8 and subtract it from 23. If the difference is a multiple of 7, then 238 is a multiple of 7.
Twice of 8 = 16
23 – 16 = 7
Since 7 is a multiple of 7, the given number 238 is a multiple of 7.
( b ) 623
To check if 623 is a multiple of 7, we must get twice 3 and subtract it from 62. If the difference is a multiple of 7, then 623 is a multiple of 7.
Twice of 3 = 6
62 – 6 = 56
Since 56 is a multiple of 7, the given number 623 is a multiple of 7.
( d ) 889
To check if 889 is a multiple of 7, we must get twice nine and subtract it from 88. If the difference is a multiple of 7, then 889 is a multiple of 7.
Twice of 9 = 18
88 – 18 = 70
Since 70 is a multiple of 7, the given number 889 is a multiple of 7.
( 3 ) 925
To check if 925 is a multiple of 7, we must get twice 5 and subtract it from 92. If the difference is a multiple of 7, then 925 is a multiple of 7.
Twice of 5 = 10
92 – 10 = 82
Since 82 is not a multiple of 7, the given number 925 is not a multiple of 7.
Examples
Example 1
Calculate the sum or total of the first five multiples of 7.
Solution
The following are the first five multiples of 7:
7, 14, 21, 28, and 35.
Hence, we have,
Sum = 7 + 14 + 21 + 28 + 35
Sum = 105
Therefore, the sum or total of the first five multiples of 7 is 105.
Example 2
Calculate the sum or total of the multiples of 7 from 1 to 100.
Solution
The following are the multiples of 7 less than 100:
7 | 14 | 21 | 28 | 35 | 42 | 49 |
56 | 63 | 70 | 77 | 84 | 91 | 98 |
Sum ( multiples of 7 from 1 to 100 ) = 735
Sum = 735
Therefore, the sum or total of the multiples of 7 less than 100 is 735.
Example 3
List down the multiples of 7 that are less than 500.
Solution
There are 71 multiples of 7 that are less than 500. The table below shows the first 71 multiples of 7.

875 | 882 | 889 | 896 | 903 | 910 | 917 | 924 | 931 | 938 |
945 | 952 | 959 | 966 | 973 | 980 | 987 | 994 |
Example 5
Solve the average of the first 20 multiples of 7.
Solution
The following are the first twenty multiples of 7:
7 | 14 | 21 | 28 | 35 | 42 | 49 | 56 | 63 | 70 |
77 | 84 | 91 | 98 | 105 | 112 | 119 | 126 | 133 | 140 |
To find the average, we must get the sum or total of these numbers and divide the answer by 20.
Sum of the first twenty multiples of 7 = 1470
Average = Sum / 20
Average = 1470 / 20
Average = 73.50
Therefore, the average of the first twenty multiples of 7 is 73.50.
Summary
Numbers that can be divided by seven precisely without any remainder are said to be multiples of seven. Let us say, for example, 56 is a multiple of seven since 56 ÷ 7 is 8.

Frequently Asked Questions on Multiples of 7 ( FAQs )
What is a multiple?
A multiple is a number resulting from multiplying one natural number or a counting number by another number.
So, for the multiples of seven, these numbers are obtained by multiplying 7 by the counting numbers. The table below shows multiplying 7 by the first ten natural numbers.
Seven Times Table |
1 × 7 = 7 |
2 × 7 = 14 |
3 × 7 = 21 |
4 × 7 = 28 |
5 × 7 = 35 |
6 × 7 = 42 |
7 × 7 = 49 |
8 × 7 = 56 |
9 × 7 = 63 |
10 × 7 = 70 |
How do we determine whether a number is a multiple of 7?
Let us observe the list of multiples of 7 below:
7 | 14 | 21 | 28 | 35 | 42 | 49 | 56 | 63 | 70 |
These are multiples of 7 because dividing each number by seven will give us a remainder of zero. That is,
7 ÷ 7 = 1
14 ÷ 7 = 2
21 ÷ 7 = 3
28 ÷ 7 = 4
35 ÷ 7 = 5
42 ÷ 7 = 6
49 ÷ 7 = 7
56 ÷ 7 = 8
63 ÷ 7 = 9
70 ÷ 7 = 10
Thus, to say that a number is a multiple of 7, it should be in the form of 7n, where n is any counting or natural number.
How many numbers are multiples of seven?
There are infinite multiples of seven. Any number created by multiplying seven by natural or counting numbers is a multiple of 7.
Start counting from zero and keep adding 7 to find multiples of 7. To find the following multiple of 7, add 7 to the multiple you already know.
