Greatest Common Divisior
We found the divisors of 258, 867, 944, 815 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 258, 867, 944, 815 is 1.
Therefore, GCD of numbers 258, 867, 944, 815 is 1
Given Input Data is 258, 867, 944, 815
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 258 is 2 x 3 x 43
Prime Factorization of 867 is 3 x 17 x 17
Prime Factorization of 944 is 2 x 2 x 2 x 2 x 59
Prime Factorization of 815 is 5 x 163
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(258, 867) = 74562
GCD(258, 867) = ( 258 x 867 ) / 74562
GCD(258, 867) = 223686 / 74562
GCD(258, 867) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 944
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 944) = 2832
GCD(3, 944) = ( 3 x 944 ) / 2832
GCD(3, 944) = 2832 / 2832
GCD(3, 944) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 815
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
GCD(1, 815) = 815 / 815
GCD(1, 815) = 1
GCD of 258, 867, 944, 815 is 1
