Given Input Data is 440, 316, 647, 280

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 316 is 2 x 2 x 79

Prime Factorization of 647 is 647

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

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, 316) = 34760

GCD(440, 316) = ( 440 x 316 ) / 34760

GCD(440, 316) = 139040 / 34760

GCD(440, 316) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 647

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

LCM(4, 647) = 2588

GCD(4, 647) = ( 4 x 647 ) / 2588

GCD(4, 647) = 2588 / 2588

GCD(4, 647) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 280

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

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

GCD(1, 280) = 280 / 280

GCD(1, 280) = 1

GCD of 440, 316, 647, 280 is 1
