Therefore, GCD of numbers 413, 385, 393, 845 is 1

Given Input Data is 413, 385, 393, 845

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

Prime Factorization of 413 is 7 x 59

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 393 is 3 x 131

Prime Factorization of 845 is 5 x 13 x 13

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(413, 385) = 22715

GCD(413, 385) = ( 413 x 385 ) / 22715

GCD(413, 385) = 159005 / 22715

GCD(413, 385) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 393

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

LCM(7, 393) = 2751

GCD(7, 393) = ( 7 x 393 ) / 2751

GCD(7, 393) = 2751 / 2751

GCD(7, 393) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 845

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

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

GCD(1, 845) = 845 / 845

GCD(1, 845) = 1

GCD of 413, 385, 393, 845 is 1
