Question

How can you express (15 30) as a multiple of a sum of whole numbers with no common factor?

Answer 1

Well theoretically speaking you could but that would take a long time and 15 and 30 have a common factor of 5 and 15. So I think for this one you can't since there are two common factors.

Answer 2

Answer with explanation:

We have to write ,15 and 30 as a multiple of sum of whole numbers with no common factor.

→15= 13+2----13 and 2 are both prime that is no factor other than 1 and itself.

→30=13 +17---13 and 17 are both prime that is no factor other than 1 and itself.
