Therefore, GCD of numbers 651, 303, 302, 813 is 1

Given Input Data is 651, 303, 302, 813

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

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 303 is 3 x 101

Prime Factorization of 302 is 2 x 151

Prime Factorization of 813 is 3 x 271

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(651, 303) = 65751

GCD(651, 303) = ( 651 x 303 ) / 65751

GCD(651, 303) = 197253 / 65751

GCD(651, 303) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 302

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

LCM(3, 302) = 906

GCD(3, 302) = ( 3 x 302 ) / 906

GCD(3, 302) = 906 / 906

GCD(3, 302) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 813

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

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

GCD(1, 813) = 813 / 813

GCD(1, 813) = 1

GCD of 651, 303, 302, 813 is 1
