Given Input Data is 156, 820, 84, 801

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

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

Prime Factorization of 820 is 2 x 2 x 5 x 41

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 801 is 3 x 3 x 89

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(156, 820) = 31980

GCD(156, 820) = ( 156 x 820 ) / 31980

GCD(156, 820) = 127920 / 31980

GCD(156, 820) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 84

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

LCM(4, 84) = 84

GCD(4, 84) = ( 4 x 84 ) / 84

GCD(4, 84) = 336 / 84

GCD(4, 84) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 801

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

LCM(4, 801) = 3204

GCD(4, 801) = ( 4 x 801 ) / 3204

GCD(4, 801) = 3204 / 3204

GCD(4, 801) = 1

GCD of 156, 820, 84, 801 is 1
