GCF & Distributive Property

Videos, solutions, and lessons to help Grade 6 students learn to**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).*

Common Core: 6.NS.4

### Least Common Multiple (LCM)

6NS4-Least Common Multiple.
Prime Factorization to Find the LCM

Break down the numbers into factors of all primes, then take the highest power of each different prime number from both your prime factorizations. Multiply them together, and you've now got the LCM/LCD for your original numbers. Finding the LCM using the "Ladder" Method.### GCF & Distributive Property
