Therefore, GCD of numbers 644, 303, 611 is 1

Given Input Data is 644, 303, 611

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

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

Prime Factorization of 303 is 3 x 101

Prime Factorization of 611 is 13 x 47

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(644, 303) = 195132

GCD(644, 303) = ( 644 x 303 ) / 195132

GCD(644, 303) = 195132 / 195132

GCD(644, 303) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 611

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

LCM(1, 611) = 611

GCD(1, 611) = ( 1 x 611 ) / 611

GCD(1, 611) = 611 / 611

GCD(1, 611) = 1

GCD of 644, 303, 611 is 1
