Question

Least common multiple of 2,7, and 13

Answer 1

All three numbers are prime so their lcm is their product.


`LCM(2,7,13)=2\cdot7\cdot13=182`

Answer 2

To work out the LCM, we need their prime factors. So:

2 is simple 2 x 1.

7 is also 7 x 1.

13 is also 13 and 1.

They all have in common "1" - so we keep that aside as 1 figure, rather than 3.

We still have the 2, 7 and 13 leftover.

We then multiply the 1 with the other figures.

So 1 x 2 x 7 x 13 is our answer.

Which is = 182.
