Therefore, GCD of numbers 990, 681, 57, 385 is 1

Given Input Data is 990, 681, 57, 385

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

Prime Factorization of 990 is 2 x 3 x 3 x 5 x 11

Prime Factorization of 681 is 3 x 227

Prime Factorization of 57 is 3 x 19

Prime Factorization of 385 is 5 x 7 x 11

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(990, 681) = 224730

GCD(990, 681) = ( 990 x 681 ) / 224730

GCD(990, 681) = 674190 / 224730

GCD(990, 681) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 57

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

LCM(3, 57) = 57

GCD(3, 57) = ( 3 x 57 ) / 57

GCD(3, 57) = 171 / 57

GCD(3, 57) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 385

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

LCM(3, 385) = 1155

GCD(3, 385) = ( 3 x 385 ) / 1155

GCD(3, 385) = 1155 / 1155

GCD(3, 385) = 1

GCD of 990, 681, 57, 385 is 1
