Given Input Data is 153, 801, 956, 655

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

Prime Factorization of 153 is 3 x 3 x 17

Prime Factorization of 801 is 3 x 3 x 89

Prime Factorization of 956 is 2 x 2 x 239

Prime Factorization of 655 is 5 x 131

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(153, 801) = 13617

GCD(153, 801) = ( 153 x 801 ) / 13617

GCD(153, 801) = 122553 / 13617

GCD(153, 801) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 956

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

LCM(9, 956) = 8604

GCD(9, 956) = ( 9 x 956 ) / 8604

GCD(9, 956) = 8604 / 8604

GCD(9, 956) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 655

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

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

GCD(1, 655) = 655 / 655

GCD(1, 655) = 1

GCD of 153, 801, 956, 655 is 1
