Given Input Data is 980, 602, 753, 639

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

Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7

Prime Factorization of 602 is 2 x 7 x 43

Prime Factorization of 753 is 3 x 251

Prime Factorization of 639 is 3 x 3 x 71

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(980, 602) = 42140

GCD(980, 602) = ( 980 x 602 ) / 42140

GCD(980, 602) = 589960 / 42140

GCD(980, 602) = 14

Step2:

Here we consider the GCD from the above i.e. 14 as first number and the next as 753

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

LCM(14, 753) = 10542

GCD(14, 753) = ( 14 x 753 ) / 10542

GCD(14, 753) = 10542 / 10542

GCD(14, 753) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 639

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

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

GCD(1, 639) = 639 / 639

GCD(1, 639) = 1

GCD of 980, 602, 753, 639 is 1
