Given Input Data is 793, 728, 515

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 793 is 13 x 61

Prime Factorization of 728 is 2 x 2 x 2 x 7 x 13

Prime Factorization of 515 is 5 x 103

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(793, 728) = 44408

GCD(793, 728) = ( 793 x 728 ) / 44408

GCD(793, 728) = 577304 / 44408

GCD(793, 728) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 515

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(13, 515) = 6695

GCD(13, 515) = ( 13 x 515 ) / 6695

GCD(13, 515) = 6695 / 6695

GCD(13, 515) = 1

GCD of 793, 728, 515 is 1
