Question

Find the least common multiple of 8y3 and 10y4

Answer 1

`40y^4`

Explanation:

To find the least common multiple (lcm) of a pair of numbers, we can multiple the numbers together and divide by the greatest common factor of those numbers. The greatest common factor (gcm) of
`8y^3` and
`10y^4` is
`2y^3`, so

`lcm(8y^3, 10y^4)=(8y^3\cdot10y^4)/(2y^3) =4\cdot10y^4=40y^4`
