We found the divisors of 78, 25, 93 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 78, 25, 93 is 1.

Therefore, GCD of numbers 78, 25, 93 is 1

Given Input Data is 78, 25, 93

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 25 is 5 x 5

Prime Factorization of 93 is 3 x 31

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, 25) = 1950

GCD(78, 25) = ( 78 x 25 ) / 1950

GCD(78, 25) = 1950 / 1950

GCD(78, 25) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 93

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

LCM(1, 93) = 93

GCD(1, 93) = ( 1 x 93 ) / 93

GCD(1, 93) = 93 / 93

GCD(1, 93) = 1

GCD of 78, 25, 93 is 1
