Greatest Common Divisior

We found the divisors of 74, 85, 15 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 74, 85, 15 is 1.

Therefore, GCD of numbers 74, 85, 15 is 1

Given Input Data is 74, 85, 15

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

Prime Factorization of 74 is 2 x 37

Prime Factorization of 85 is 5 x 17

Prime Factorization of 15 is 3 x 5

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(74, 85) = 6290

GCD(74, 85) = ( 74 x 85 ) / 6290

GCD(74, 85) = 6290 / 6290

GCD(74, 85) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

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

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 1

GCD of 74, 85, 15 is 1
