So the Greatest Common Divisior 414, 657, 430, 617 is 1.

Therefore, GCD of numbers 414, 657, 430, 617 is 1

Given Input Data is 414, 657, 430, 617

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 657 is 3 x 3 x 73

Prime Factorization of 430 is 2 x 5 x 43

Prime Factorization of 617 is 617

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, 657) = 30222

GCD(414, 657) = ( 414 x 657 ) / 30222

GCD(414, 657) = 271998 / 30222

GCD(414, 657) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 430

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

LCM(9, 430) = 3870

GCD(9, 430) = ( 9 x 430 ) / 3870

GCD(9, 430) = 3870 / 3870

GCD(9, 430) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 617

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

LCM(1, 617) = 617

GCD(1, 617) = ( 1 x 617 ) / 617

GCD(1, 617) = 617 / 617

GCD(1, 617) = 1

GCD of 414, 657, 430, 617 is 1
