Given Input Data is 87, 459, 840, 519

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

Prime Factorization of 87 is 3 x 29

Prime Factorization of 459 is 3 x 3 x 3 x 17

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

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(87, 459) = 13311

GCD(87, 459) = ( 87 x 459 ) / 13311

GCD(87, 459) = 39933 / 13311

GCD(87, 459) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 840

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

LCM(3, 840) = 840

GCD(3, 840) = ( 3 x 840 ) / 840

GCD(3, 840) = 2520 / 840

GCD(3, 840) = 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 87, 459, 840, 519 is 3
