So the Greatest Common Divisior 36, 80, 82, 30 is 2.

Therefore, GCD of numbers 36, 80, 82, 30 is 2

Given Input Data is 36, 80, 82, 30

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

Prime Factorization of 36 is 2 x 2 x 3 x 3

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 82 is 2 x 41

Prime Factorization of 30 is 2 x 3 x 5

Highest common occurrences in the given inputs are 2¹

Multiplying them we get the GCD as 2

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(36, 80) = 720

GCD(36, 80) = ( 36 x 80 ) / 720

GCD(36, 80) = 2880 / 720

GCD(36, 80) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 82

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

LCM(4, 82) = 164

GCD(4, 82) = ( 4 x 82 ) / 164

GCD(4, 82) = 328 / 164

GCD(4, 82) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 30

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

LCM(2, 30) = 30

GCD(2, 30) = ( 2 x 30 ) / 30

GCD(2, 30) = 60 / 30

GCD(2, 30) = 2

GCD of 36, 80, 82, 30 is 2
