Given Input Data is 985, 290, 507, 663

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

Prime Factorization of 985 is 5 x 197

Prime Factorization of 290 is 2 x 5 x 29

Prime Factorization of 507 is 3 x 13 x 13

Prime Factorization of 663 is 3 x 13 x 17

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(985, 290) = 57130

GCD(985, 290) = ( 985 x 290 ) / 57130

GCD(985, 290) = 285650 / 57130

GCD(985, 290) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 507

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

LCM(5, 507) = 2535

GCD(5, 507) = ( 5 x 507 ) / 2535

GCD(5, 507) = 2535 / 2535

GCD(5, 507) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 663

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

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

GCD(1, 663) = 663 / 663

GCD(1, 663) = 1

GCD of 985, 290, 507, 663 is 1
