Therefore, GCD of numbers 221, 525, 787 is 1

Given Input Data is 221, 525, 787

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

Prime Factorization of 221 is 13 x 17

Prime Factorization of 525 is 3 x 5 x 5 x 7

Prime Factorization of 787 is 787

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, 525) = 116025

GCD(221, 525) = ( 221 x 525 ) / 116025

GCD(221, 525) = 116025 / 116025

GCD(221, 525) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 787

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

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

GCD(1, 787) = 787 / 787

GCD(1, 787) = 1

GCD of 221, 525, 787 is 1
