Therefore, GCD of numbers 221, 250, 77 is 1

Given Input Data is 221, 250, 77

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

Prime Factorization of 221 is 13 x 17

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

Prime Factorization of 77 is 7 x 11

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(221, 250) = 55250

GCD(221, 250) = ( 221 x 250 ) / 55250

GCD(221, 250) = 55250 / 55250

GCD(221, 250) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 77

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

LCM(1, 77) = 77

GCD(1, 77) = ( 1 x 77 ) / 77

GCD(1, 77) = 77 / 77

GCD(1, 77) = 1

GCD of 221, 250, 77 is 1
