Given Input Data is 203, 518, 749

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

Prime Factorization of 203 is 7 x 29

Prime Factorization of 518 is 2 x 7 x 37

Prime Factorization of 749 is 7 x 107

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(203, 518) = 15022

GCD(203, 518) = ( 203 x 518 ) / 15022

GCD(203, 518) = 105154 / 15022

GCD(203, 518) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 749

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

LCM(7, 749) = 749

GCD(7, 749) = ( 7 x 749 ) / 749

GCD(7, 749) = 5243 / 749

GCD(7, 749) = 7

GCD of 203, 518, 749 is 7
