GCD of two numbers is 17 and their LCM is 140.If one of the numbers is 20,find the other number

Let the required number be x.

We have a formula,

Product of two numbers = (Their LCM) (Their HCF)

or, 20x = (140)(17)

or, x = 7(17) = 119

So the required number is 119

answer: x=60

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer
