Greatest Common Divisior

We found the divisors of 75, 82, 72 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 75, 82, 72 is 1.

Therefore, GCD of numbers 75, 82, 72 is 1

Given Input Data is 75, 82, 72

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

Prime Factorization of 75 is 3 x 5 x 5

Prime Factorization of 82 is 2 x 41

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

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

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(75, 82) = 6150

GCD(75, 82) = ( 75 x 82 ) / 6150

GCD(75, 82) = 6150 / 6150

GCD(75, 82) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 72

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

LCM(1, 72) = 72

GCD(1, 72) = ( 1 x 72 ) / 72

GCD(1, 72) = 72 / 72

GCD(1, 72) = 1

GCD of 75, 82, 72 is 1
