So the Greatest Common Divisior 13, 67, 85 is 1.

Therefore, GCD of numbers 13, 67, 85 is 1

Given Input Data is 13, 67, 85

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

Prime Factorization of 13 is 13

Prime Factorization of 67 is 67

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(13, 67) = 871

GCD(13, 67) = ( 13 x 67 ) / 871

GCD(13, 67) = 871 / 871

GCD(13, 67) = 1

Step2:

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 13, 67, 85 is 1
