Therefore, GCD of numbers 231, 686, 10, 847 is 1

Given Input Data is 231, 686, 10, 847

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

Prime Factorization of 231 is 3 x 7 x 11

Prime Factorization of 686 is 2 x 7 x 7 x 7

Prime Factorization of 10 is 2 x 5

Prime Factorization of 847 is 7 x 11 x 11

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(231, 686) = 22638

GCD(231, 686) = ( 231 x 686 ) / 22638

GCD(231, 686) = 158466 / 22638

GCD(231, 686) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 10

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

LCM(7, 10) = 70

GCD(7, 10) = ( 7 x 10 ) / 70

GCD(7, 10) = 70 / 70

GCD(7, 10) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 847

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

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

GCD(1, 847) = 847 / 847

GCD(1, 847) = 1

GCD of 231, 686, 10, 847 is 1
