Therefore, GCD of numbers 21, 579, 593, 650 is 1

Given Input Data is 21, 579, 593, 650

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

Prime Factorization of 21 is 3 x 7

Prime Factorization of 579 is 3 x 193

Prime Factorization of 593 is 593

Prime Factorization of 650 is 2 x 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, 579) = 4053

GCD(21, 579) = ( 21 x 579 ) / 4053

GCD(21, 579) = 12159 / 4053

GCD(21, 579) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 593

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

LCM(3, 593) = 1779

GCD(3, 593) = ( 3 x 593 ) / 1779

GCD(3, 593) = 1779 / 1779

GCD(3, 593) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 650

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

LCM(1, 650) = 650

GCD(1, 650) = ( 1 x 650 ) / 650

GCD(1, 650) = 650 / 650

GCD(1, 650) = 1

GCD of 21, 579, 593, 650 is 1
