Therefore, GCD of numbers 393, 579, 84, 775 is 1

Given Input Data is 393, 579, 84, 775

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

Prime Factorization of 393 is 3 x 131

Prime Factorization of 579 is 3 x 193

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 775 is 5 x 5 x 31

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(393, 579) = 75849

GCD(393, 579) = ( 393 x 579 ) / 75849

GCD(393, 579) = 227547 / 75849

GCD(393, 579) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 84

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

LCM(3, 84) = 84

GCD(3, 84) = ( 3 x 84 ) / 84

GCD(3, 84) = 252 / 84

GCD(3, 84) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 775

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

LCM(3, 775) = 2325

GCD(3, 775) = ( 3 x 775 ) / 2325

GCD(3, 775) = 2325 / 2325

GCD(3, 775) = 1

GCD of 393, 579, 84, 775 is 1
