Given Input Data is 656, 948, 13, 790

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

Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41

Prime Factorization of 948 is 2 x 2 x 3 x 79

Prime Factorization of 13 is 13

Prime Factorization of 790 is 2 x 5 x 79

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(656, 948) = 155472

GCD(656, 948) = ( 656 x 948 ) / 155472

GCD(656, 948) = 621888 / 155472

GCD(656, 948) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 13

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

LCM(4, 13) = 52

GCD(4, 13) = ( 4 x 13 ) / 52

GCD(4, 13) = 52 / 52

GCD(4, 13) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 790

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

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

GCD(1, 790) = 790 / 790

GCD(1, 790) = 1

GCD of 656, 948, 13, 790 is 1
