Finding GCD of 905, 580, 861 using Prime Factorization

Given Input Data is 905, 580, 861

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

Prime Factorization of 905 is 5 x 181

Prime Factorization of 580 is 2 x 2 x 5 x 29

Prime Factorization of 861 is 3 x 7 x 41

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

Finding GCD of 905, 580, 861 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(905, 580) = 104980

GCD(905, 580) = ( 905 x 580 ) / 104980

GCD(905, 580) = 524900 / 104980

GCD(905, 580) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 861

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

LCM(5, 861) = 4305

GCD(5, 861) = ( 5 x 861 ) / 4305

GCD(5, 861) = 4305 / 4305

GCD(5, 861) = 1

GCD of 905, 580, 861 is 1
