Given Input Data is 404, 780, 628

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

Prime Factorization of 404 is 2 x 2 x 101

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

Prime Factorization of 628 is 2 x 2 x 157

Highest common occurrences in the given inputs are 2²

Multiplying them we get the GCD as 4

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(404, 780) = 78780

GCD(404, 780) = ( 404 x 780 ) / 78780

GCD(404, 780) = 315120 / 78780

GCD(404, 780) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 628

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

LCM(4, 628) = 628

GCD(4, 628) = ( 4 x 628 ) / 628

GCD(4, 628) = 2512 / 628

GCD(4, 628) = 4

GCD of 404, 780, 628 is 4
