Given Input Data is 975, 642, 626

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

Prime Factorization of 975 is 3 x 5 x 5 x 13

Prime Factorization of 642 is 2 x 3 x 107

Prime Factorization of 626 is 2 x 313

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(975, 642) = 208650

GCD(975, 642) = ( 975 x 642 ) / 208650

GCD(975, 642) = 625950 / 208650

GCD(975, 642) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 626

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

LCM(3, 626) = 1878

GCD(3, 626) = ( 3 x 626 ) / 1878

GCD(3, 626) = 1878 / 1878

GCD(3, 626) = 1

GCD of 975, 642, 626 is 1
