Given Input Data is 988, 666, 973, 715

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

Prime Factorization of 988 is 2 x 2 x 13 x 19

Prime Factorization of 666 is 2 x 3 x 3 x 37

Prime Factorization of 973 is 7 x 139

Prime Factorization of 715 is 5 x 11 x 13

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(988, 666) = 329004

GCD(988, 666) = ( 988 x 666 ) / 329004

GCD(988, 666) = 658008 / 329004

GCD(988, 666) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 973

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

LCM(2, 973) = 1946

GCD(2, 973) = ( 2 x 973 ) / 1946

GCD(2, 973) = 1946 / 1946

GCD(2, 973) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 715

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

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

GCD(1, 715) = 715 / 715

GCD(1, 715) = 1

GCD of 988, 666, 973, 715 is 1
