Therefore, GCD of numbers 399, 817, 48, 486 is 1

Given Input Data is 399, 817, 48, 486

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 817 is 19 x 43

Prime Factorization of 48 is 2 x 2 x 2 x 2 x 3

Prime Factorization of 486 is 2 x 3 x 3 x 3 x 3 x 3

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, 817) = 17157

GCD(399, 817) = ( 399 x 817 ) / 17157

GCD(399, 817) = 325983 / 17157

GCD(399, 817) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 48

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

LCM(19, 48) = 912

GCD(19, 48) = ( 19 x 48 ) / 912

GCD(19, 48) = 912 / 912

GCD(19, 48) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 486

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

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

GCD(1, 486) = 486 / 486

GCD(1, 486) = 1

GCD of 399, 817, 48, 486 is 1
