Answer 1

B. 60

Explanation:

To find the least common multiple of 10 and 60, all you have to do is find the prime factorization for both.

10 = 5 x 2

60 = 5 x 3 x 2 x 2

LCM = 2 x 2 x 3 x 5

= 60

Answer 2

B. 60

Explanation:

10 X 6 = 60

60 X 1 = 60

Anything below 10 X 6 is too low to be LCM
