Therefore, GCD of numbers 509, 820, 502 is 1

Given Input Data is 509, 820, 502

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

Prime Factorization of 509 is 509

Prime Factorization of 820 is 2 x 2 x 5 x 41

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(509, 820) = 417380

GCD(509, 820) = ( 509 x 820 ) / 417380

GCD(509, 820) = 417380 / 417380

GCD(509, 820) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 502

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

LCM(1, 502) = 502

GCD(1, 502) = ( 1 x 502 ) / 502

GCD(1, 502) = 502 / 502

GCD(1, 502) = 1

GCD of 509, 820, 502 is 1
