Question

Find the least common multiple of these two expressions. 15x^7y^3u^8 and 6y^4u^5

Answer 1

`30x^7y^4u^8`

Explanation:

We have been given two expressions
`15x^7y^3u^8` and

`6y^4u^5`

Now we need to find out least common multiple of these two expressions.

First we need to find out what is common factor of both expressions.
`15x^7y^3u^8` and

`6y^4u^5`

Least common multiple means find the expression which can be divided by both expressions.

15 and 6 both goes into 30

so 30 is part of LCM (least common multiple )

Now pickup the highest exponent of each variable.

So we get
`x^7y^4u^8`

Hence required least common multiple is
`30x^7y^4u^8`
