The various resources listed below are aligned to the same standard, (6NS04) taken from the CCSM (Common Core Standards For Mathematics) as the Factors and multiples Worksheet shown above.

Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1-100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4 (9 + 2). Apply and extend previous understandings of numbers to the system of rational numbers.
