Finding GCD of 155, 422, 641 using Prime Factorization

Given Input Data is 155, 422, 641

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

Prime Factorization of 155 is 5 x 31

Prime Factorization of 422 is 2 x 211

Prime Factorization of 641 is 641

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

Finding GCD of 155, 422, 641 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(155, 422) = 65410

GCD(155, 422) = ( 155 x 422 ) / 65410

GCD(155, 422) = 65410 / 65410

GCD(155, 422) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 641

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

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

GCD(1, 641) = 641 / 641

GCD(1, 641) = 1

GCD of 155, 422, 641 is 1
