So the Greatest Common Divisior 815, 788, 904, 879 is 1.

Therefore, GCD of numbers 815, 788, 904, 879 is 1

Given Input Data is 815, 788, 904, 879

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

Prime Factorization of 815 is 5 x 163

Prime Factorization of 788 is 2 x 2 x 197

Prime Factorization of 904 is 2 x 2 x 2 x 113

Prime Factorization of 879 is 3 x 293

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(815, 788) = 642220

GCD(815, 788) = ( 815 x 788 ) / 642220

GCD(815, 788) = 642220 / 642220

GCD(815, 788) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 904

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

LCM(1, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

GCD(1, 904) = 904 / 904

GCD(1, 904) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 879

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

LCM(1, 879) = 879

GCD(1, 879) = ( 1 x 879 ) / 879

GCD(1, 879) = 879 / 879

GCD(1, 879) = 1

GCD of 815, 788, 904, 879 is 1
