Therefore, GCD of numbers 351, 564, 21, 566 is 1

Given Input Data is 351, 564, 21, 566

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

Prime Factorization of 351 is 3 x 3 x 3 x 13

Prime Factorization of 564 is 2 x 2 x 3 x 47

Prime Factorization of 21 is 3 x 7

Prime Factorization of 566 is 2 x 283

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(351, 564) = 65988

GCD(351, 564) = ( 351 x 564 ) / 65988

GCD(351, 564) = 197964 / 65988

GCD(351, 564) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 21

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

LCM(3, 21) = 21

GCD(3, 21) = ( 3 x 21 ) / 21

GCD(3, 21) = 63 / 21

GCD(3, 21) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 566

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

LCM(3, 566) = 1698

GCD(3, 566) = ( 3 x 566 ) / 1698

GCD(3, 566) = 1698 / 1698

GCD(3, 566) = 1

GCD of 351, 564, 21, 566 is 1
