Question

Use prime factorization to find the LCM of 10 and 12

Answer 1

10=2*5
12=2*2*3

they both have a 2 so we take that out and are left with 5,3, & 2. this can be confusing, but when there is a pair you use the number in the pair. so if there is a pair of 2, the number we use is a 2

2*2*5*3=60
