Given Input Data is 20, 156, 581, 846

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

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 156 is 2 x 2 x 3 x 13

Prime Factorization of 581 is 7 x 83

Prime Factorization of 846 is 2 x 3 x 3 x 47

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(20, 156) = 780

GCD(20, 156) = ( 20 x 156 ) / 780

GCD(20, 156) = 3120 / 780

GCD(20, 156) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 581

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

LCM(4, 581) = 2324

GCD(4, 581) = ( 4 x 581 ) / 2324

GCD(4, 581) = 2324 / 2324

GCD(4, 581) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 846

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

LCM(1, 846) = 846

GCD(1, 846) = ( 1 x 846 ) / 846

GCD(1, 846) = 846 / 846

GCD(1, 846) = 1

GCD of 20, 156, 581, 846 is 1
