Given Input Data is 819, 339, 999, 456

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

Prime Factorization of 819 is 3 x 3 x 7 x 13

Prime Factorization of 339 is 3 x 113

Prime Factorization of 999 is 3 x 3 x 3 x 37

Prime Factorization of 456 is 2 x 2 x 2 x 3 x 19

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(819, 339) = 92547

GCD(819, 339) = ( 819 x 339 ) / 92547

GCD(819, 339) = 277641 / 92547

GCD(819, 339) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 999

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

LCM(3, 999) = 999

GCD(3, 999) = ( 3 x 999 ) / 999

GCD(3, 999) = 2997 / 999

GCD(3, 999) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 456

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

LCM(3, 456) = 456

GCD(3, 456) = ( 3 x 456 ) / 456

GCD(3, 456) = 1368 / 456

GCD(3, 456) = 3

GCD of 819, 339, 999, 456 is 3
