Given Input Data is 652, 280, 458, 515

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

Prime Factorization of 652 is 2 x 2 x 163

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

Prime Factorization of 458 is 2 x 229

Prime Factorization of 515 is 5 x 103

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(652, 280) = 45640

GCD(652, 280) = ( 652 x 280 ) / 45640

GCD(652, 280) = 182560 / 45640

GCD(652, 280) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 458

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

LCM(4, 458) = 916

GCD(4, 458) = ( 4 x 458 ) / 916

GCD(4, 458) = 1832 / 916

GCD(4, 458) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 515

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

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

GCD(2, 515) = 1030 / 1030

GCD(2, 515) = 1

GCD of 652, 280, 458, 515 is 1
