Therefore, GCD of numbers 681, 746, 85, 479 is 1

Given Input Data is 681, 746, 85, 479

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

Prime Factorization of 681 is 3 x 227

Prime Factorization of 746 is 2 x 373

Prime Factorization of 85 is 5 x 17

Prime Factorization of 479 is 479

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(681, 746) = 508026

GCD(681, 746) = ( 681 x 746 ) / 508026

GCD(681, 746) = 508026 / 508026

GCD(681, 746) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 85

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

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

GCD(1, 85) = 85 / 85

GCD(1, 85) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 479

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

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

GCD(1, 479) = 479 / 479

GCD(1, 479) = 1

GCD of 681, 746, 85, 479 is 1
