Therefore, GCD of numbers 609, 847, 80, 631 is 1

Given Input Data is 609, 847, 80, 631

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

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 847 is 7 x 11 x 11

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 631 is 631

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(609, 847) = 73689

GCD(609, 847) = ( 609 x 847 ) / 73689

GCD(609, 847) = 515823 / 73689

GCD(609, 847) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 80

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

LCM(7, 80) = 560

GCD(7, 80) = ( 7 x 80 ) / 560

GCD(7, 80) = 560 / 560

GCD(7, 80) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 631

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

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

GCD(1, 631) = 631 / 631

GCD(1, 631) = 1

GCD of 609, 847, 80, 631 is 1
