We found the divisors of 414, 415, 99, 817 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 414, 415, 99, 817 is 1.

Therefore, GCD of numbers 414, 415, 99, 817 is 1

Given Input Data is 414, 415, 99, 817

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

Prime Factorization of 414 is 2 x 3 x 3 x 23

Prime Factorization of 415 is 5 x 83

Prime Factorization of 99 is 3 x 3 x 11

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(414, 415) = 171810

GCD(414, 415) = ( 414 x 415 ) / 171810

GCD(414, 415) = 171810 / 171810

GCD(414, 415) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 99

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

LCM(1, 99) = 99

GCD(1, 99) = ( 1 x 99 ) / 99

GCD(1, 99) = 99 / 99

GCD(1, 99) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 817

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

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

GCD(1, 817) = 817 / 817

GCD(1, 817) = 1

GCD of 414, 415, 99, 817 is 1
