Therefore, GCD of numbers 250, 894, 721 is 1

Given Input Data is 250, 894, 721

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 894 is 2 x 3 x 149

Prime Factorization of 721 is 7 x 103

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, 894) = 111750

GCD(250, 894) = ( 250 x 894 ) / 111750

GCD(250, 894) = 223500 / 111750

GCD(250, 894) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 721

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

LCM(2, 721) = 1442

GCD(2, 721) = ( 2 x 721 ) / 1442

GCD(2, 721) = 1442 / 1442

GCD(2, 721) = 1

GCD of 250, 894, 721 is 1
