Given Input Data is 621, 177, 659

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

Prime Factorization of 621 is 3 x 3 x 3 x 23

Prime Factorization of 177 is 3 x 59

Prime Factorization of 659 is 659

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(621, 177) = 36639

GCD(621, 177) = ( 621 x 177 ) / 36639

GCD(621, 177) = 109917 / 36639

GCD(621, 177) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 659

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

LCM(3, 659) = 1977

GCD(3, 659) = ( 3 x 659 ) / 1977

GCD(3, 659) = 1977 / 1977

GCD(3, 659) = 1

GCD of 621, 177, 659 is 1
