Therefore, GCD of numbers 21, 939, 910, 325 is 1

Given Input Data is 21, 939, 910, 325

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

Prime Factorization of 21 is 3 x 7

Prime Factorization of 939 is 3 x 313

Prime Factorization of 910 is 2 x 5 x 7 x 13

Prime Factorization of 325 is 5 x 5 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(21, 939) = 6573

GCD(21, 939) = ( 21 x 939 ) / 6573

GCD(21, 939) = 19719 / 6573

GCD(21, 939) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 910

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

LCM(3, 910) = 2730

GCD(3, 910) = ( 3 x 910 ) / 2730

GCD(3, 910) = 2730 / 2730

GCD(3, 910) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 325

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

LCM(1, 325) = 325

GCD(1, 325) = ( 1 x 325 ) / 325

GCD(1, 325) = 325 / 325

GCD(1, 325) = 1

GCD of 21, 939, 910, 325 is 1
