Therefore, GCD of numbers 217, 875, 55, 530 is 1

Given Input Data is 217, 875, 55, 530

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

Prime Factorization of 217 is 7 x 31

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

Prime Factorization of 55 is 5 x 11

Prime Factorization of 530 is 2 x 5 x 53

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(217, 875) = 27125

GCD(217, 875) = ( 217 x 875 ) / 27125

GCD(217, 875) = 189875 / 27125

GCD(217, 875) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 55

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

LCM(7, 55) = 385

GCD(7, 55) = ( 7 x 55 ) / 385

GCD(7, 55) = 385 / 385

GCD(7, 55) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 530

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

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

GCD(1, 530) = 530 / 530

GCD(1, 530) = 1

GCD of 217, 875, 55, 530 is 1
