Finding GCD of 963, 647, 77 using Prime Factorization

Given Input Data is 963, 647, 77

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

Prime Factorization of 963 is 3 x 3 x 107

Prime Factorization of 647 is 647

Prime Factorization of 77 is 7 x 11

The above numbers do not have any common prime factor. So GCD is 1

Finding GCD of 963, 647, 77 using LCM Formula

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(963, 647) = 623061

GCD(963, 647) = ( 963 x 647 ) / 623061

GCD(963, 647) = 623061 / 623061

GCD(963, 647) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 77

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

LCM(1, 77) = 77

GCD(1, 77) = ( 1 x 77 ) / 77

GCD(1, 77) = 77 / 77

GCD(1, 77) = 1

GCD of 963, 647, 77 is 1
