We found the divisors of 681, 119, 90, 658 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 681, 119, 90, 658 is 1.

Therefore, GCD of numbers 681, 119, 90, 658 is 1

Given Input Data is 681, 119, 90, 658

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

Prime Factorization of 681 is 3 x 227

Prime Factorization of 119 is 7 x 17

Prime Factorization of 90 is 2 x 3 x 3 x 5

Prime Factorization of 658 is 2 x 7 x 47

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, 119) = 81039

GCD(681, 119) = ( 681 x 119 ) / 81039

GCD(681, 119) = 81039 / 81039

GCD(681, 119) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 90

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

LCM(1, 90) = 90

GCD(1, 90) = ( 1 x 90 ) / 90

GCD(1, 90) = 90 / 90

GCD(1, 90) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 658

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

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

GCD(1, 658) = 658 / 658

GCD(1, 658) = 1

GCD of 681, 119, 90, 658 is 1
