Greatest Common Divisior

We found the divisors of 80, 38, 29, 40 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 80, 38, 29, 40 is 1.

Therefore, GCD of numbers 80, 38, 29, 40 is 1

Finding GCD of 80, 38, 29, 40 using Prime Factorization

Given Input Data is 80, 38, 29, 40

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

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

Prime Factorization of 38 is 2 x 19

Prime Factorization of 29 is 29

Prime Factorization of 40 is 2 x 2 x 2 x 5

The above numbers do not have any common prime factor. So GCD is 1

Finding GCD of 80, 38, 29, 40 using LCM Formula

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(80, 38) = 1520

GCD(80, 38) = ( 80 x 38 ) / 1520

GCD(80, 38) = 3040 / 1520

GCD(80, 38) = 2


Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 29

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

LCM(2, 29) = 58

GCD(2, 29) = ( 2 x 29 ) / 58

GCD(2, 29) = 58 / 58

GCD(2, 29) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 40

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

LCM(1, 40) = 40

GCD(1, 40) = ( 1 x 40 ) / 40

GCD(1, 40) = 40 / 40

GCD(1, 40) = 1

GCD of 80, 38, 29, 40 is 1
