Therefore, GCD of numbers 640, 484, 63, 108 is 1

Given Input Data is 640, 484, 63, 108

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 484 is 2 x 2 x 11 x 11

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 108 is 2 x 2 x 3 x 3 x 3

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, 484) = 77440

GCD(640, 484) = ( 640 x 484 ) / 77440

GCD(640, 484) = 309760 / 77440

GCD(640, 484) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 63

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

LCM(4, 63) = 252

GCD(4, 63) = ( 4 x 63 ) / 252

GCD(4, 63) = 252 / 252

GCD(4, 63) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 108

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

LCM(1, 108) = 108

GCD(1, 108) = ( 1 x 108 ) / 108

GCD(1, 108) = 108 / 108

GCD(1, 108) = 1

GCD of 640, 484, 63, 108 is 1
