We found the divisors of 84, 19, 26, 81 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 84, 19, 26, 81 is 1.

Therefore, GCD of numbers 84, 19, 26, 81 is 1

Given Input Data is 84, 19, 26, 81

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

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

Prime Factorization of 19 is 19

Prime Factorization of 26 is 2 x 13

Prime Factorization of 81 is 3 x 3 x 3 x 3

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(84, 19) = 1596

GCD(84, 19) = ( 84 x 19 ) / 1596

GCD(84, 19) = 1596 / 1596

GCD(84, 19) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 26

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

LCM(1, 26) = 26

GCD(1, 26) = ( 1 x 26 ) / 26

GCD(1, 26) = 26 / 26

GCD(1, 26) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 81

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

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

GCD(1, 81) = 81 / 81

GCD(1, 81) = 1

GCD of 84, 19, 26, 81 is 1
