What's the least common multiple of 24 and 36?
This time, we'll go with the second method for finding the LCM. First list the prime factors of both numbers.
24= 2 x 2 x 2 x 3
36= 2 x 2 x 3 x 3
The greatest number of times 2 appears is three times (in 24) and the greatest number of times 3 appears is twice (in 36).
So the LCM
is 2 x 2 x 2 x 3 x 3 = 72
