Given Input Data is 625, 210, 642, 806

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

Prime Factorization of 625 is 5 x 5 x 5 x 5

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 642 is 2 x 3 x 107

Prime Factorization of 806 is 2 x 13 x 31

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(625, 210) = 26250

GCD(625, 210) = ( 625 x 210 ) / 26250

GCD(625, 210) = 131250 / 26250

GCD(625, 210) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 642

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

LCM(5, 642) = 3210

GCD(5, 642) = ( 5 x 642 ) / 3210

GCD(5, 642) = 3210 / 3210

GCD(5, 642) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 806

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

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

GCD(1, 806) = 806 / 806

GCD(1, 806) = 1

GCD of 625, 210, 642, 806 is 1
