What is the factor tree for 36?
Instead of expressing 36 as 2 × 18, we can express 36 as 6 × 6. Prime factorization of 36 using factor tree method is 2 × 2 × 3 × 3 = 2² × 3².
What pair of numbers has an LCM of 18?
When we overlap these two restrictions, we see that the only values common to both sets are 6 and 18. So our possible pairs are (6,6) , (6,18) , or (18,18) . But wait—only one of these pairs has both an LCM of 18 and a GCF of 6. That pair is (6,18) .
