We found the divisors of 69, 15, 37 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 69, 15, 37 is 1.

Therefore, GCD of numbers 69, 15, 37 is 1

Given Input Data is 69, 15, 37

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

Prime Factorization of 69 is 3 x 23

Prime Factorization of 15 is 3 x 5

Prime Factorization of 37 is 37

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(69, 15) = 345

GCD(69, 15) = ( 69 x 15 ) / 345

GCD(69, 15) = 1035 / 345

GCD(69, 15) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 37

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

LCM(3, 37) = 111

GCD(3, 37) = ( 3 x 37 ) / 111

GCD(3, 37) = 111 / 111

GCD(3, 37) = 1

GCD of 69, 15, 37 is 1
