Therefore, GCD of numbers 975, 465, 499, 640 is 1

Given Input Data is 975, 465, 499, 640

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

Prime Factorization of 975 is 3 x 5 x 5 x 13

Prime Factorization of 465 is 3 x 5 x 31

Prime Factorization of 499 is 499

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

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(975, 465) = 30225

GCD(975, 465) = ( 975 x 465 ) / 30225

GCD(975, 465) = 453375 / 30225

GCD(975, 465) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 499

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

LCM(15, 499) = 7485

GCD(15, 499) = ( 15 x 499 ) / 7485

GCD(15, 499) = 7485 / 7485

GCD(15, 499) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 640

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

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

GCD(1, 640) = 640 / 640

GCD(1, 640) = 1

GCD of 975, 465, 499, 640 is 1
