Greatest Common Divisior
We found the divisors of 312, 865, 203, 915 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 312, 865, 203, 915 is 1.
Therefore, GCD of numbers 312, 865, 203, 915 is 1
Given Input Data is 312, 865, 203, 915
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 312 is 2 x 2 x 2 x 3 x 13
Prime Factorization of 865 is 5 x 173
Prime Factorization of 203 is 7 x 29
Prime Factorization of 915 is 3 x 5 x 61
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(312, 865) = 269880
GCD(312, 865) = ( 312 x 865 ) / 269880
GCD(312, 865) = 269880 / 269880
GCD(312, 865) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 203
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 203) = 203
GCD(1, 203) = ( 1 x 203 ) / 203
GCD(1, 203) = 203 / 203
GCD(1, 203) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 915
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
GCD(1, 915) = 915 / 915
GCD(1, 915) = 1
GCD of 312, 865, 203, 915 is 1
