Given Input Data is 627, 345, 81, 519

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

Prime Factorization of 627 is 3 x 11 x 19

Prime Factorization of 345 is 3 x 5 x 23

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 519 is 3 x 173

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(627, 345) = 72105

GCD(627, 345) = ( 627 x 345 ) / 72105

GCD(627, 345) = 216315 / 72105

GCD(627, 345) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 81

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

LCM(3, 81) = 81

GCD(3, 81) = ( 3 x 81 ) / 81

GCD(3, 81) = 243 / 81

GCD(3, 81) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 519

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

LCM(3, 519) = 519

GCD(3, 519) = ( 3 x 519 ) / 519

GCD(3, 519) = 1557 / 519

GCD(3, 519) = 3

GCD of 627, 345, 81, 519 is 3
