We found the divisors of 78, 99, 92, 79 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 78, 99, 92, 79 is 1.

Therefore, GCD of numbers 78, 99, 92, 79 is 1

Given Input Data is 78, 99, 92, 79

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

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 99 is 3 x 3 x 11

Prime Factorization of 92 is 2 x 2 x 23

Prime Factorization of 79 is 79

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(78, 99) = 2574

GCD(78, 99) = ( 78 x 99 ) / 2574

GCD(78, 99) = 7722 / 2574

GCD(78, 99) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 92

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

LCM(3, 92) = 276

GCD(3, 92) = ( 3 x 92 ) / 276

GCD(3, 92) = 276 / 276

GCD(3, 92) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 79

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

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

GCD(1, 79) = 79 / 79

GCD(1, 79) = 1

GCD of 78, 99, 92, 79 is 1
