Therefore, GCD of numbers 789, 111, 875, 217 is 1

Given Input Data is 789, 111, 875, 217

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

Prime Factorization of 789 is 3 x 263

Prime Factorization of 111 is 3 x 37

Prime Factorization of 875 is 5 x 5 x 5 x 7

Prime Factorization of 217 is 7 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(789, 111) = 29193

GCD(789, 111) = ( 789 x 111 ) / 29193

GCD(789, 111) = 87579 / 29193

GCD(789, 111) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 875

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

LCM(3, 875) = 2625

GCD(3, 875) = ( 3 x 875 ) / 2625

GCD(3, 875) = 2625 / 2625

GCD(3, 875) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 217

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

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

GCD(1, 217) = 217 / 217

GCD(1, 217) = 1

GCD of 789, 111, 875, 217 is 1
