Given Input Data is 147, 812, 839, 816

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

Prime Factorization of 147 is 3 x 7 x 7

Prime Factorization of 812 is 2 x 2 x 7 x 29

Prime Factorization of 839 is 839

Prime Factorization of 816 is 2 x 2 x 2 x 2 x 3 x 17

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(147, 812) = 17052

GCD(147, 812) = ( 147 x 812 ) / 17052

GCD(147, 812) = 119364 / 17052

GCD(147, 812) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 839

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

LCM(7, 839) = 5873

GCD(7, 839) = ( 7 x 839 ) / 5873

GCD(7, 839) = 5873 / 5873

GCD(7, 839) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 816

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

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

GCD(1, 816) = 816 / 816

GCD(1, 816) = 1

GCD of 147, 812, 839, 816 is 1
