Given Input Data is 520, 195, 443, 354

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 195 is 3 x 5 x 13

Prime Factorization of 443 is 443

Prime Factorization of 354 is 2 x 3 x 59

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(520, 195) = 1560

GCD(520, 195) = ( 520 x 195 ) / 1560

GCD(520, 195) = 101400 / 1560

GCD(520, 195) = 65

Step2:

Here we consider the GCD from the above i.e. 65 as first number and the next as 443

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

LCM(65, 443) = 28795

GCD(65, 443) = ( 65 x 443 ) / 28795

GCD(65, 443) = 28795 / 28795

GCD(65, 443) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 354

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

LCM(1, 354) = 354

GCD(1, 354) = ( 1 x 354 ) / 354

GCD(1, 354) = 354 / 354

GCD(1, 354) = 1

GCD of 520, 195, 443, 354 is 1
