Given Input Data is 665, 220, 502

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

Prime Factorization of 665 is 5 x 7 x 19

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 502 is 2 x 251

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(665, 220) = 29260

GCD(665, 220) = ( 665 x 220 ) / 29260

GCD(665, 220) = 146300 / 29260

GCD(665, 220) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 502

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

LCM(5, 502) = 2510

GCD(5, 502) = ( 5 x 502 ) / 2510

GCD(5, 502) = 2510 / 2510

GCD(5, 502) = 1

GCD of 665, 220, 502 is 1
