Given Input Data is 660, 535, 104, 249

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

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 535 is 5 x 107

Prime Factorization of 104 is 2 x 2 x 2 x 13

Prime Factorization of 249 is 3 x 83

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(660, 535) = 70620

GCD(660, 535) = ( 660 x 535 ) / 70620

GCD(660, 535) = 353100 / 70620

GCD(660, 535) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 104

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

LCM(5, 104) = 520

GCD(5, 104) = ( 5 x 104 ) / 520

GCD(5, 104) = 520 / 520

GCD(5, 104) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 249

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

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

GCD(1, 249) = 249 / 249

GCD(1, 249) = 1

GCD of 660, 535, 104, 249 is 1
