Greatest Common Divisior

We found the divisors of 76, 90, 23, 73 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 76, 90, 23, 73 is 1.

Therefore, GCD of numbers 76, 90, 23, 73 is 1

Given Input Data is 76, 90, 23, 73

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

Prime Factorization of 76 is 2 x 2 x 19

Prime Factorization of 90 is 2 x 3 x 3 x 5

Prime Factorization of 23 is 23

Prime Factorization of 73 is 73

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(76, 90) = 3420

GCD(76, 90) = ( 76 x 90 ) / 3420

GCD(76, 90) = 6840 / 3420

GCD(76, 90) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 23

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

LCM(2, 23) = 46

GCD(2, 23) = ( 2 x 23 ) / 46

GCD(2, 23) = 46 / 46

GCD(2, 23) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 73

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

LCM(1, 73) = 73

GCD(1, 73) = ( 1 x 73 ) / 73

GCD(1, 73) = 73 / 73

GCD(1, 73) = 1

GCD of 76, 90, 23, 73 is 1
