Finding GCD of 391, 173, 617 using Prime Factorization

Given Input Data is 391, 173, 617

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

Prime Factorization of 391 is 17 x 23

Prime Factorization of 173 is 173

Prime Factorization of 617 is 617

The above numbers do not have any common prime factor. So GCD is 1

Finding GCD of 391, 173, 617 using LCM Formula

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(391, 173) = 67643

GCD(391, 173) = ( 391 x 173 ) / 67643

GCD(391, 173) = 67643 / 67643

GCD(391, 173) = 1

Step2:

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 391, 173, 617 is 1
