Therefore, GCD of numbers 855, 530, 24, 268 is 1

Given Input Data is 855, 530, 24, 268

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

Prime Factorization of 855 is 3 x 3 x 5 x 19

Prime Factorization of 530 is 2 x 5 x 53

Prime Factorization of 24 is 2 x 2 x 2 x 3

Prime Factorization of 268 is 2 x 2 x 67

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(855, 530) = 90630

GCD(855, 530) = ( 855 x 530 ) / 90630

GCD(855, 530) = 453150 / 90630

GCD(855, 530) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 24

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

LCM(5, 24) = 120

GCD(5, 24) = ( 5 x 24 ) / 120

GCD(5, 24) = 120 / 120

GCD(5, 24) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 268

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

LCM(1, 268) = 268

GCD(1, 268) = ( 1 x 268 ) / 268

GCD(1, 268) = 268 / 268

GCD(1, 268) = 1

GCD of 855, 530, 24, 268 is 1
