Given Input Data is 721, 588, 623

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

Prime Factorization of 721 is 7 x 103

Prime Factorization of 588 is 2 x 2 x 3 x 7 x 7

Prime Factorization of 623 is 7 x 89

Highest common occurrences in the given inputs are 7¹

Multiplying them we get the GCD as 7

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(721, 588) = 60564

GCD(721, 588) = ( 721 x 588 ) / 60564

GCD(721, 588) = 423948 / 60564

GCD(721, 588) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 623

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

LCM(7, 623) = 623

GCD(7, 623) = ( 7 x 623 ) / 623

GCD(7, 623) = 4361 / 623

GCD(7, 623) = 7

GCD of 721, 588, 623 is 7
