Therefore, GCD of numbers 404, 221, 777 is 1

Given Input Data is 404, 221, 777

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

Prime Factorization of 404 is 2 x 2 x 101

Prime Factorization of 221 is 13 x 17

Prime Factorization of 777 is 3 x 7 x 37

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(404, 221) = 89284

GCD(404, 221) = ( 404 x 221 ) / 89284

GCD(404, 221) = 89284 / 89284

GCD(404, 221) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 777

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

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

GCD(1, 777) = 777 / 777

GCD(1, 777) = 1

GCD of 404, 221, 777 is 1
