Therefore, GCD of numbers 351, 555, 81, 817 is 1

Given Input Data is 351, 555, 81, 817

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 555 is 3 x 5 x 37

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 817 is 19 x 43

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, 555) = 64935

GCD(351, 555) = ( 351 x 555 ) / 64935

GCD(351, 555) = 194805 / 64935

GCD(351, 555) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 81

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

LCM(3, 81) = 81

GCD(3, 81) = ( 3 x 81 ) / 81

GCD(3, 81) = 243 / 81

GCD(3, 81) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 817

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

LCM(3, 817) = 2451

GCD(3, 817) = ( 3 x 817 ) / 2451

GCD(3, 817) = 2451 / 2451

GCD(3, 817) = 1

GCD of 351, 555, 81, 817 is 1
