Therefore, GCD of numbers 831, 942, 815 is 1

Given Input Data is 831, 942, 815

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

Prime Factorization of 831 is 3 x 277

Prime Factorization of 942 is 2 x 3 x 157

Prime Factorization of 815 is 5 x 163

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(831, 942) = 260934

GCD(831, 942) = ( 831 x 942 ) / 260934

GCD(831, 942) = 782802 / 260934

GCD(831, 942) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 815

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

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

GCD(3, 815) = 2445 / 2445

GCD(3, 815) = 1

GCD of 831, 942, 815 is 1
