Given Input Data is 553, 329, 25, 156

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

Prime Factorization of 553 is 7 x 79

Prime Factorization of 329 is 7 x 47

Prime Factorization of 25 is 5 x 5

Prime Factorization of 156 is 2 x 2 x 3 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(553, 329) = 25991

GCD(553, 329) = ( 553 x 329 ) / 25991

GCD(553, 329) = 181937 / 25991

GCD(553, 329) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 25

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

LCM(7, 25) = 175

GCD(7, 25) = ( 7 x 25 ) / 175

GCD(7, 25) = 175 / 175

GCD(7, 25) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 156

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

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

GCD(1, 156) = 156 / 156

GCD(1, 156) = 1

GCD of 553, 329, 25, 156 is 1
