Therefore, GCD of numbers 650, 385, 39, 509 is 1

Given Input Data is 650, 385, 39, 509

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

Prime Factorization of 650 is 2 x 5 x 5 x 13

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 39 is 3 x 13

Prime Factorization of 509 is 509

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(650, 385) = 50050

GCD(650, 385) = ( 650 x 385 ) / 50050

GCD(650, 385) = 250250 / 50050

GCD(650, 385) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 39

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

LCM(5, 39) = 195

GCD(5, 39) = ( 5 x 39 ) / 195

GCD(5, 39) = 195 / 195

GCD(5, 39) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 509

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

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

GCD(1, 509) = 509 / 509

GCD(1, 509) = 1

GCD of 650, 385, 39, 509 is 1
