Therefore, GCD of numbers 655, 455, 418 is 1

Given Input Data is 655, 455, 418

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

Prime Factorization of 655 is 5 x 131

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 418 is 2 x 11 x 19

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(655, 455) = 59605

GCD(655, 455) = ( 655 x 455 ) / 59605

GCD(655, 455) = 298025 / 59605

GCD(655, 455) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 418

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

LCM(5, 418) = 2090

GCD(5, 418) = ( 5 x 418 ) / 2090

GCD(5, 418) = 2090 / 2090

GCD(5, 418) = 1

GCD of 655, 455, 418 is 1
