Question

How do you find the Least common multiple of `20y, 14y^2`?

Answer 1

`LCM = 2^2*5*7*y^2=140y^2`

Explanation:

Factorize the two expressions:

`20y=2^2*5*y`
`14y^2=2*7*y^2`

The LCM is the product of all factors - common or not common - taken once with the highest exponent.

`LCM = 2^2*5*7*y^2=140y^2`
