Therefore, GCD of numbers 957, 657, 661 is 1

Given Input Data is 957, 657, 661

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

Prime Factorization of 957 is 3 x 11 x 29

Prime Factorization of 657 is 3 x 3 x 73

Prime Factorization of 661 is 661

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(957, 657) = 209583

GCD(957, 657) = ( 957 x 657 ) / 209583

GCD(957, 657) = 628749 / 209583

GCD(957, 657) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 661

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

LCM(3, 661) = 1983

GCD(3, 661) = ( 3 x 661 ) / 1983

GCD(3, 661) = 1983 / 1983

GCD(3, 661) = 1

GCD of 957, 657, 661 is 1
