Question

How do you find the Least common multiple of 35, 25?

Answer 1

LCM = 175

Explanation:

With LCM questions, I first start with a prime factorization of the numbers in question:

`35=5xx7`
`25=5xx5`

The LCM will have all the elements contained within the numbers above, so it'll have the two 5's from 25 and the 7 from 35 (the 5 in 35 is already counted in the 5's coming from the 25). It works out to be:

`5xx5xx7=25xx7=175`

`35xx5=175`
`25xx7=175`
