Therefore, GCD of numbers 441, 931, 85, 513 is 1

Given Input Data is 441, 931, 85, 513

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

Prime Factorization of 441 is 3 x 3 x 7 x 7

Prime Factorization of 931 is 7 x 7 x 19

Prime Factorization of 85 is 5 x 17

Prime Factorization of 513 is 3 x 3 x 3 x 19

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(441, 931) = 8379

GCD(441, 931) = ( 441 x 931 ) / 8379

GCD(441, 931) = 410571 / 8379

GCD(441, 931) = 49

Step2:

Here we consider the GCD from the above i.e. 49 as first number and the next as 85

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

LCM(49, 85) = 4165

GCD(49, 85) = ( 49 x 85 ) / 4165

GCD(49, 85) = 4165 / 4165

GCD(49, 85) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 513

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

LCM(1, 513) = 513

GCD(1, 513) = ( 1 x 513 ) / 513

GCD(1, 513) = 513 / 513

GCD(1, 513) = 1

GCD of 441, 931, 85, 513 is 1
