Given Input Data is 440, 636, 98, 451

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

Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 98 is 2 x 7 x 7

Prime Factorization of 451 is 11 x 41

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(440, 636) = 69960

GCD(440, 636) = ( 440 x 636 ) / 69960

GCD(440, 636) = 279840 / 69960

GCD(440, 636) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 98

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

LCM(4, 98) = 196

GCD(4, 98) = ( 4 x 98 ) / 196

GCD(4, 98) = 392 / 196

GCD(4, 98) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 451

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

LCM(2, 451) = 902

GCD(2, 451) = ( 2 x 451 ) / 902

GCD(2, 451) = 902 / 902

GCD(2, 451) = 1

GCD of 440, 636, 98, 451 is 1
