Answer 2

Answer:

1. The first multiple that 8 and 12 have in common is 24.

2. The least common multiple of 13 and 91 is 91 because 91 is the smallest number that is divisible by 13 and 91.

3. The least multiple on the two lists that they have in common is the LCM of 14 and 63. Therefore, the LCM of 14 and 63 is 126.

4. the lcm of 21 and 45 can be found using the prime factorization that is 315.

5. Least common multiple (LCM) of 9 and 27 is 27.

6. Least common multiple (LCM) of 12 and 19 is 228.
