Given Input Data is 655, 630, 158, 939

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

Prime Factorization of 655 is 5 x 131

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 158 is 2 x 79

Prime Factorization of 939 is 3 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(655, 630) = 82530

GCD(655, 630) = ( 655 x 630 ) / 82530

GCD(655, 630) = 412650 / 82530

GCD(655, 630) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 158

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

LCM(5, 158) = 790

GCD(5, 158) = ( 5 x 158 ) / 790

GCD(5, 158) = 790 / 790

GCD(5, 158) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 939

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

LCM(1, 939) = 939

GCD(1, 939) = ( 1 x 939 ) / 939

GCD(1, 939) = 939 / 939

GCD(1, 939) = 1

GCD of 655, 630, 158, 939 is 1
