Therefore, GCD of numbers 127, 170, 397 is 1

Given Input Data is 127, 170, 397

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

Prime Factorization of 127 is 127

Prime Factorization of 170 is 2 x 5 x 17

Prime Factorization of 397 is 397

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(127, 170) = 21590

GCD(127, 170) = ( 127 x 170 ) / 21590

GCD(127, 170) = 21590 / 21590

GCD(127, 170) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 397

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

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

GCD(1, 397) = 397 / 397

GCD(1, 397) = 1

GCD of 127, 170, 397 is 1
