Question

What is the LCM of 35, 14, 10?

Answer 1

LCM is `70`.

Explanation:

Prime factors of `35` are `5xx7`

those of `14` are `2xx7`

and of `10` are `2xx5`

Now for LCM just pick up all the prime numbers and they should be repeated the maximum number of times they appear as a factor of any single number.

Here `2`, `5` and `7` have appeared not more than once,

hence, LCM is `2xx5xx7=70`.
