So the Greatest Common Divisior 54, 54, 19, 85 is 1.

Therefore, GCD of numbers 54, 54, 19, 85 is 1

Given Input Data is 54, 54, 19, 85

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

Prime Factorization of 54 is 2 x 3 x 3 x 3

Prime Factorization of 54 is 2 x 3 x 3 x 3

Prime Factorization of 19 is 19

Prime Factorization of 85 is 5 x 17

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(54, 54) = 54

GCD(54, 54) = ( 54 x 54 ) / 54

GCD(54, 54) = 2916 / 54

GCD(54, 54) = 54

Step2:

Here we consider the GCD from the above i.e. 54 as first number and the next as 19

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

LCM(54, 19) = 1026

GCD(54, 19) = ( 54 x 19 ) / 1026

GCD(54, 19) = 1026 / 1026

GCD(54, 19) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 85

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

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

GCD(1, 85) = 85 / 85

GCD(1, 85) = 1

GCD of 54, 54, 19, 85 is 1
