We found the divisors of 415, 515, 78, 368 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 415, 515, 78, 368 is 1.

Therefore, GCD of numbers 415, 515, 78, 368 is 1

Given Input Data is 415, 515, 78, 368

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

Prime Factorization of 415 is 5 x 83

Prime Factorization of 515 is 5 x 103

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 368 is 2 x 2 x 2 x 2 x 23

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(415, 515) = 42745

GCD(415, 515) = ( 415 x 515 ) / 42745

GCD(415, 515) = 213725 / 42745

GCD(415, 515) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 78

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

LCM(5, 78) = 390

GCD(5, 78) = ( 5 x 78 ) / 390

GCD(5, 78) = 390 / 390

GCD(5, 78) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 368

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

LCM(1, 368) = 368

GCD(1, 368) = ( 1 x 368 ) / 368

GCD(1, 368) = 368 / 368

GCD(1, 368) = 1

GCD of 415, 515, 78, 368 is 1
