So the Greatest Common Divisior 86, 18, 84, 79 is 1.

Therefore, GCD of numbers 86, 18, 84, 79 is 1

Given Input Data is 86, 18, 84, 79

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

Prime Factorization of 86 is 2 x 43

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 84 is 2 x 2 x 3 x 7

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(86, 18) = 774

GCD(86, 18) = ( 86 x 18 ) / 774

GCD(86, 18) = 1548 / 774

GCD(86, 18) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 84

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

LCM(2, 84) = 84

GCD(2, 84) = ( 2 x 84 ) / 84

GCD(2, 84) = 168 / 84

GCD(2, 84) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 79

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

LCM(2, 79) = 158

GCD(2, 79) = ( 2 x 79 ) / 158

GCD(2, 79) = 158 / 158

GCD(2, 79) = 1

GCD of 86, 18, 84, 79 is 1
