Therefore, GCD of numbers 711, 399, 15, 824 is 1

Given Input Data is 711, 399, 15, 824

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

Prime Factorization of 711 is 3 x 3 x 79

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 15 is 3 x 5

Prime Factorization of 824 is 2 x 2 x 2 x 103

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(711, 399) = 94563

GCD(711, 399) = ( 711 x 399 ) / 94563

GCD(711, 399) = 283689 / 94563

GCD(711, 399) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 15

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

LCM(3, 15) = 15

GCD(3, 15) = ( 3 x 15 ) / 15

GCD(3, 15) = 45 / 15

GCD(3, 15) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 824

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

LCM(3, 824) = 2472

GCD(3, 824) = ( 3 x 824 ) / 2472

GCD(3, 824) = 2472 / 2472

GCD(3, 824) = 1

GCD of 711, 399, 15, 824 is 1
