Question

The ratio of two no's is 5:7, and their H.C.F is 13, find the no's​

Answer 1

: Let the numbers be A and B.

: So A:B= 5:7

Since GCD, the greatest common divisor is 13, the two numbers will be the multiples of 5 and 7 respectively.

Other than GCD, no other number will be common to both numbers.

: So A= 13 x 5= 65 and

: B= 13 x 7= 91

So the numbers are 65 and 91
