Given Input Data is 621, 644, 134

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 644 is 2 x 2 x 7 x 23

Prime Factorization of 134 is 2 x 67

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, 644) = 17388

GCD(621, 644) = ( 621 x 644 ) / 17388

GCD(621, 644) = 399924 / 17388

GCD(621, 644) = 23

Step2:

Here we consider the GCD from the above i.e. 23 as first number and the next as 134

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

LCM(23, 134) = 3082

GCD(23, 134) = ( 23 x 134 ) / 3082

GCD(23, 134) = 3082 / 3082

GCD(23, 134) = 1

GCD of 621, 644, 134 is 1
