Greatest Common Divisior

We found the divisors of 76, 9, 19, 75 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 76, 9, 19, 75 is 1.

Therefore, GCD of numbers 76, 9, 19, 75 is 1

Given Input Data is 76, 9, 19, 75

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 9 is 3 x 3

Prime Factorization of 19 is 19

Prime Factorization of 75 is 3 x 5 x 5

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, 9) = 684

GCD(76, 9) = ( 76 x 9 ) / 684

GCD(76, 9) = 684 / 684

GCD(76, 9) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 19

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

LCM(1, 19) = 19

GCD(1, 19) = ( 1 x 19 ) / 19

GCD(1, 19) = 19 / 19

GCD(1, 19) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 75

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

LCM(1, 75) = 75

GCD(1, 75) = ( 1 x 75 ) / 75

GCD(1, 75) = 75 / 75

GCD(1, 75) = 1

GCD of 76, 9, 19, 75 is 1
