What is the least common multiple of A and B?
Another way to say this is:
\lcm(A, B) = {?}
LCM
The least common multiple is the smallest number that is a multiple of A and B.
We know that A \times B (or PRODUCT) is a common multiple,
but is it the least common multiple?
Write out the multiples of BIGGER until we find a number divisible by SMALLER.
M,
So, the least common multiple of A and B is LCM.
