Given Input Data is 903, 405, 591

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

Prime Factorization of 903 is 3 x 7 x 43

Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5

Prime Factorization of 591 is 3 x 197

Highest common occurrences in the given inputs are 3¹

Multiplying them we get the GCD as 3

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(903, 405) = 121905

GCD(903, 405) = ( 903 x 405 ) / 121905

GCD(903, 405) = 365715 / 121905

GCD(903, 405) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 591

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

LCM(3, 591) = 591

GCD(3, 591) = ( 3 x 591 ) / 591

GCD(3, 591) = 1773 / 591

GCD(3, 591) = 3

GCD of 903, 405, 591 is 3
