Therefore, GCD of numbers 579, 620, 563 is 1

Given Input Data is 579, 620, 563

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

Prime Factorization of 579 is 3 x 193

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 563 is 563

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(579, 620) = 358980

GCD(579, 620) = ( 579 x 620 ) / 358980

GCD(579, 620) = 358980 / 358980

GCD(579, 620) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 563

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

LCM(1, 563) = 563

GCD(1, 563) = ( 1 x 563 ) / 563

GCD(1, 563) = 563 / 563

GCD(1, 563) = 1

GCD of 579, 620, 563 is 1
