Given Input Data is 520, 428, 380

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

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

Prime Factorization of 428 is 2 x 2 x 107

Prime Factorization of 380 is 2 x 2 x 5 x 19

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(520, 428) = 55640

GCD(520, 428) = ( 520 x 428 ) / 55640

GCD(520, 428) = 222560 / 55640

GCD(520, 428) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 380

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

LCM(4, 380) = 380

GCD(4, 380) = ( 4 x 380 ) / 380

GCD(4, 380) = 1520 / 380

GCD(4, 380) = 4

GCD of 520, 428, 380 is 4
