Greatest Common Divisior
We found the divisors of 278, 403, 797 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 278, 403, 797 is 1.
Therefore, GCD of numbers 278, 403, 797 is 1
Given Input Data is 278, 403, 797
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 278 is 2 x 139
Prime Factorization of 403 is 13 x 31
Prime Factorization of 797 is 797
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(278, 403) = 112034
GCD(278, 403) = ( 278 x 403 ) / 112034
GCD(278, 403) = 112034 / 112034
GCD(278, 403) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 797
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 797) = 797
GCD(1, 797) = ( 1 x 797 ) / 797
GCD(1, 797) = 797 / 797
GCD(1, 797) = 1
GCD of 278, 403, 797 is 1
