Therefore, GCD of numbers 399, 567, 19, 956 is 1

Given Input Data is 399, 567, 19, 956

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

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 567 is 3 x 3 x 3 x 3 x 7

Prime Factorization of 19 is 19

Prime Factorization of 956 is 2 x 2 x 239

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(399, 567) = 10773

GCD(399, 567) = ( 399 x 567 ) / 10773

GCD(399, 567) = 226233 / 10773

GCD(399, 567) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 19

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

LCM(21, 19) = 399

GCD(21, 19) = ( 21 x 19 ) / 399

GCD(21, 19) = 399 / 399

GCD(21, 19) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 956

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

LCM(1, 956) = 956

GCD(1, 956) = ( 1 x 956 ) / 956

GCD(1, 956) = 956 / 956

GCD(1, 956) = 1

GCD of 399, 567, 19, 956 is 1
