Greatest Common Divisior

We found the divisors of 30, 44, 56, 80 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 30, 44, 56, 80 is 2.

Therefore, GCD of numbers 30, 44, 56, 80 is 2

Given Input Data is 30, 44, 56, 80

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

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 44 is 2 x 2 x 11

Prime Factorization of 56 is 2 x 2 x 2 x 7

Prime Factorization of 80 is 2 x 2 x 2 x 2 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(30, 44) = 660

GCD(30, 44) = ( 30 x 44 ) / 660

GCD(30, 44) = 1320 / 660

GCD(30, 44) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 56

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

LCM(2, 56) = 56

GCD(2, 56) = ( 2 x 56 ) / 56

GCD(2, 56) = 112 / 56

GCD(2, 56) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 80

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

LCM(2, 80) = 80

GCD(2, 80) = ( 2 x 80 ) / 80

GCD(2, 80) = 160 / 80

GCD(2, 80) = 2

GCD of 30, 44, 56, 80 is 2
