We found the divisors of 86, 29, 78 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 86, 29, 78 is 1.

Therefore, GCD of numbers 86, 29, 78 is 1

Given Input Data is 86, 29, 78

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

Prime Factorization of 86 is 2 x 43

Prime Factorization of 29 is 29

Prime Factorization of 78 is 2 x 3 x 13

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(86, 29) = 2494

GCD(86, 29) = ( 86 x 29 ) / 2494

GCD(86, 29) = 2494 / 2494

GCD(86, 29) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 78

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

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

GCD(1, 78) = 78 / 78

GCD(1, 78) = 1

GCD of 86, 29, 78 is 1
