Given Input Data is 985, 220, 459, 838

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

Prime Factorization of 985 is 5 x 197

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

Prime Factorization of 459 is 3 x 3 x 3 x 17

Prime Factorization of 838 is 2 x 419

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, 220) = 43340

GCD(985, 220) = ( 985 x 220 ) / 43340

GCD(985, 220) = 216700 / 43340

GCD(985, 220) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 459

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

LCM(5, 459) = 2295

GCD(5, 459) = ( 5 x 459 ) / 2295

GCD(5, 459) = 2295 / 2295

GCD(5, 459) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 838

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

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

GCD(1, 838) = 838 / 838

GCD(1, 838) = 1

GCD of 985, 220, 459, 838 is 1
