Given Input Data is 520, 836, 787, 242

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 836 is 2 x 2 x 11 x 19

Prime Factorization of 787 is 787

Prime Factorization of 242 is 2 x 11 x 11

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, 836) = 108680

GCD(520, 836) = ( 520 x 836 ) / 108680

GCD(520, 836) = 434720 / 108680

GCD(520, 836) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 787

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

LCM(4, 787) = 3148

GCD(4, 787) = ( 4 x 787 ) / 3148

GCD(4, 787) = 3148 / 3148

GCD(4, 787) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 242

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

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

GCD(1, 242) = 242 / 242

GCD(1, 242) = 1

GCD of 520, 836, 787, 242 is 1
