Given Input Data is 780, 656, 181

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

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41

Prime Factorization of 181 is 181

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(780, 656) = 127920

GCD(780, 656) = ( 780 x 656 ) / 127920

GCD(780, 656) = 511680 / 127920

GCD(780, 656) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 181

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

LCM(4, 181) = 724

GCD(4, 181) = ( 4 x 181 ) / 724

GCD(4, 181) = 724 / 724

GCD(4, 181) = 1

GCD of 780, 656, 181 is 1
