Therefore, GCD of numbers 250, 445, 644 is 1

Given Input Data is 250, 445, 644

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

Prime Factorization of 250 is 2 x 5 x 5 x 5

Prime Factorization of 445 is 5 x 89

Prime Factorization of 644 is 2 x 2 x 7 x 23

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(250, 445) = 22250

GCD(250, 445) = ( 250 x 445 ) / 22250

GCD(250, 445) = 111250 / 22250

GCD(250, 445) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 644

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

LCM(5, 644) = 3220

GCD(5, 644) = ( 5 x 644 ) / 3220

GCD(5, 644) = 3220 / 3220

GCD(5, 644) = 1

GCD of 250, 445, 644 is 1
