Therefore, GCD of numbers 974, 644, 517 is 1

Given Input Data is 974, 644, 517

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

Prime Factorization of 974 is 2 x 487

Prime Factorization of 644 is 2 x 2 x 7 x 23

Prime Factorization of 517 is 11 x 47

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(974, 644) = 313628

GCD(974, 644) = ( 974 x 644 ) / 313628

GCD(974, 644) = 627256 / 313628

GCD(974, 644) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 517

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

LCM(2, 517) = 1034

GCD(2, 517) = ( 2 x 517 ) / 1034

GCD(2, 517) = 1034 / 1034

GCD(2, 517) = 1

GCD of 974, 644, 517 is 1
