Therefore, GCD of numbers 147, 644, 157 is 1

Given Input Data is 147, 644, 157

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

Prime Factorization of 147 is 3 x 7 x 7

Prime Factorization of 644 is 2 x 2 x 7 x 23

Prime Factorization of 157 is 157

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(147, 644) = 13524

GCD(147, 644) = ( 147 x 644 ) / 13524

GCD(147, 644) = 94668 / 13524

GCD(147, 644) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 157

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

LCM(7, 157) = 1099

GCD(7, 157) = ( 7 x 157 ) / 1099

GCD(7, 157) = 1099 / 1099

GCD(7, 157) = 1

GCD of 147, 644, 157 is 1
