Given Input Data is 51, 837, 621, 390

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

Prime Factorization of 51 is 3 x 17

Prime Factorization of 837 is 3 x 3 x 3 x 31

Prime Factorization of 621 is 3 x 3 x 3 x 23

Prime Factorization of 390 is 2 x 3 x 5 x 13

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(51, 837) = 14229

GCD(51, 837) = ( 51 x 837 ) / 14229

GCD(51, 837) = 42687 / 14229

GCD(51, 837) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 621

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

LCM(3, 621) = 621

GCD(3, 621) = ( 3 x 621 ) / 621

GCD(3, 621) = 1863 / 621

GCD(3, 621) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 390

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

LCM(3, 390) = 390

GCD(3, 390) = ( 3 x 390 ) / 390

GCD(3, 390) = 1170 / 390

GCD(3, 390) = 3

GCD of 51, 837, 621, 390 is 3
