Given Input Data is 640, 112, 549

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

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 112 is 2 x 2 x 2 x 2 x 7

Prime Factorization of 549 is 3 x 3 x 61

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(640, 112) = 4480

GCD(640, 112) = ( 640 x 112 ) / 4480

GCD(640, 112) = 71680 / 4480

GCD(640, 112) = 16

Step2:

Here we consider the GCD from the above i.e. 16 as first number and the next as 549

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

LCM(16, 549) = 8784

GCD(16, 549) = ( 16 x 549 ) / 8784

GCD(16, 549) = 8784 / 8784

GCD(16, 549) = 1

GCD of 640, 112, 549 is 1
