Therefore, GCD of numbers 15, 462, 239, 871 is 1

Given Input Data is 15, 462, 239, 871

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

Prime Factorization of 15 is 3 x 5

Prime Factorization of 462 is 2 x 3 x 7 x 11

Prime Factorization of 239 is 239

Prime Factorization of 871 is 13 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(15, 462) = 2310

GCD(15, 462) = ( 15 x 462 ) / 2310

GCD(15, 462) = 6930 / 2310

GCD(15, 462) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 239

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

LCM(3, 239) = 717

GCD(3, 239) = ( 3 x 239 ) / 717

GCD(3, 239) = 717 / 717

GCD(3, 239) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 871

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

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

GCD(1, 871) = 871 / 871

GCD(1, 871) = 1

GCD of 15, 462, 239, 871 is 1
