How do you get the answer least common multiple 152 and 212?

Answer 1

Even if one assumes that you meant "common multiples" and not "commen multiplules", it is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!

Furthermore, the word "least" is superlative and that means that there can be only one such number for a given set of numbers. So the question should be about "common multiple", not "common multiples".

Answer 2

Factor them.

2 x 2 x 2 x 19 = 152

2 x 2 x 53 = 212

Combine the highest amount of each factor.

2 x 2 x 2 x 19 x 53 = 8056, the LCM.
