How do you find the least common multiple or the lcm of 10 and 8

40

Step-by-step explanation:

Least common multiple (lcm) = the smallest multiple that both numbers have.

Let's figure it out.

10 = 2 x 5

8 = 2 x 2 x 2

the ones I have highlighted, we will multiply them all together, except for a 2.

we didn't multiply one of the 2's because they both have a two, so we only keep one of them.

so it is 2 x 5 x 2 x 2

let me say it again, because they both share a same 2, that one is eliminated.

so the answer is 40 because:

2 x 5 x 2 x 2

= 10 x 4

= 40
