Question

Define least common multiple of two numbers

Answer 1

i think the name speaks for itself.

Answer 2

Definitions are hard to give tips on because there isn't a whole lot I could say that could help you remember what it is if you don't already know it. With that being said:

Least common multiple - let's break it apart.

"Least" - meaning "Smallest"
"Common" - meaning "Shared"
As for the word "Multiple" - here are some examples:
Multiples of 5 are numbers like - 5, 10, 15, 20, 25, 30, and so on.

So what you're looking for is the smallest number that two numbers have in common.
