Therefore, GCD of numbers 417, 638, 432 is 1

Given Input Data is 417, 638, 432

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

Prime Factorization of 417 is 3 x 139

Prime Factorization of 638 is 2 x 11 x 29

Prime Factorization of 432 is 2 x 2 x 2 x 2 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(417, 638) = 266046

GCD(417, 638) = ( 417 x 638 ) / 266046

GCD(417, 638) = 266046 / 266046

GCD(417, 638) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 432

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

LCM(1, 432) = 432

GCD(1, 432) = ( 1 x 432 ) / 432

GCD(1, 432) = 432 / 432

GCD(1, 432) = 1

GCD of 417, 638, 432 is 1
