Therefore, GCD of numbers 326, 628, 387 is 1

Given Input Data is 326, 628, 387

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

Prime Factorization of 326 is 2 x 163

Prime Factorization of 628 is 2 x 2 x 157

Prime Factorization of 387 is 3 x 3 x 43

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(326, 628) = 102364

GCD(326, 628) = ( 326 x 628 ) / 102364

GCD(326, 628) = 204728 / 102364

GCD(326, 628) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 387

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

LCM(2, 387) = 774

GCD(2, 387) = ( 2 x 387 ) / 774

GCD(2, 387) = 774 / 774

GCD(2, 387) = 1

GCD of 326, 628, 387 is 1
