Therefore, GCD of numbers 250, 156, 155 is 1

Given Input Data is 250, 156, 155

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 156 is 2 x 2 x 3 x 13

Prime Factorization of 155 is 5 x 31

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, 156) = 19500

GCD(250, 156) = ( 250 x 156 ) / 19500

GCD(250, 156) = 39000 / 19500

GCD(250, 156) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 155

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

LCM(2, 155) = 310

GCD(2, 155) = ( 2 x 155 ) / 310

GCD(2, 155) = 310 / 310

GCD(2, 155) = 1

GCD of 250, 156, 155 is 1
