Given Input Data is 808, 860, 775, 651

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

Prime Factorization of 808 is 2 x 2 x 2 x 101

Prime Factorization of 860 is 2 x 2 x 5 x 43

Prime Factorization of 775 is 5 x 5 x 31

Prime Factorization of 651 is 3 x 7 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(808, 860) = 173720

GCD(808, 860) = ( 808 x 860 ) / 173720

GCD(808, 860) = 694880 / 173720

GCD(808, 860) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 775

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

LCM(4, 775) = 3100

GCD(4, 775) = ( 4 x 775 ) / 3100

GCD(4, 775) = 3100 / 3100

GCD(4, 775) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 651

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

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

GCD(1, 651) = 651 / 651

GCD(1, 651) = 1

GCD of 808, 860, 775, 651 is 1
