Therefore, GCD of numbers 640, 888, 35, 287 is 1

Given Input Data is 640, 888, 35, 287

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 888 is 2 x 2 x 2 x 3 x 37

Prime Factorization of 35 is 5 x 7

Prime Factorization of 287 is 7 x 41

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, 888) = 71040

GCD(640, 888) = ( 640 x 888 ) / 71040

GCD(640, 888) = 568320 / 71040

GCD(640, 888) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 35

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

LCM(8, 35) = 280

GCD(8, 35) = ( 8 x 35 ) / 280

GCD(8, 35) = 280 / 280

GCD(8, 35) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 287

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

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

GCD(1, 287) = 287 / 287

GCD(1, 287) = 1

GCD of 640, 888, 35, 287 is 1
