# Common Factors & HCF

Identifying the factors of a number, factor pairs, finding common factors for 2 numbers and their highest common factor. Solving word problems using these concepts.

#### Mapped to CCSS Section# 4.OA.B.4, 6.NS.B.4

Find all factor pairs for a whole number in the range 1- 100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1- 100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1- 100 is prime or composite.,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)..
