Given Input Data is 825, 489, 803

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

Prime Factorization of 825 is 3 x 5 x 5 x 11

Prime Factorization of 489 is 3 x 163

Prime Factorization of 803 is 11 x 73

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(825, 489) = 134475

GCD(825, 489) = ( 825 x 489 ) / 134475

GCD(825, 489) = 403425 / 134475

GCD(825, 489) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 803

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

LCM(3, 803) = 2409

GCD(3, 803) = ( 3 x 803 ) / 2409

GCD(3, 803) = 2409 / 2409

GCD(3, 803) = 1

GCD of 825, 489, 803 is 1
