Given Input Data is 861, 833, 100, 931

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

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 833 is 7 x 7 x 17

Prime Factorization of 100 is 2 x 2 x 5 x 5

Prime Factorization of 931 is 7 x 7 x 19

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(861, 833) = 102459

GCD(861, 833) = ( 861 x 833 ) / 102459

GCD(861, 833) = 717213 / 102459

GCD(861, 833) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 100

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

LCM(7, 100) = 700

GCD(7, 100) = ( 7 x 100 ) / 700

GCD(7, 100) = 700 / 700

GCD(7, 100) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 931

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

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

GCD(1, 931) = 931 / 931

GCD(1, 931) = 1

GCD of 861, 833, 100, 931 is 1
