Greatest Common Divisior

We found the divisors of 14, 77, 15 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 14, 77, 15 is 1.

Therefore, GCD of numbers 14, 77, 15 is 1

Given Input Data is 14, 77, 15

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

Prime Factorization of 14 is 2 x 7

Prime Factorization of 77 is 7 x 11

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(14, 77) = 154

GCD(14, 77) = ( 14 x 77 ) / 154

GCD(14, 77) = 1078 / 154

GCD(14, 77) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 15

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

LCM(7, 15) = 105

GCD(7, 15) = ( 7 x 15 ) / 105

GCD(7, 15) = 105 / 105

GCD(7, 15) = 1

GCD of 14, 77, 15 is 1
