Therefore, GCD of numbers 934, 860, 396, 645 is 1

Given Input Data is 934, 860, 396, 645

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

Prime Factorization of 934 is 2 x 467

Prime Factorization of 860 is 2 x 2 x 5 x 43

Prime Factorization of 396 is 2 x 2 x 3 x 3 x 11

Prime Factorization of 645 is 3 x 5 x 43

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(934, 860) = 401620

GCD(934, 860) = ( 934 x 860 ) / 401620

GCD(934, 860) = 803240 / 401620

GCD(934, 860) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 396

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

LCM(2, 396) = 396

GCD(2, 396) = ( 2 x 396 ) / 396

GCD(2, 396) = 792 / 396

GCD(2, 396) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 645

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

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

GCD(2, 645) = 1290 / 1290

GCD(2, 645) = 1

GCD of 934, 860, 396, 645 is 1
