1, 2, 5, 10, 67, 134, 335, 670
Greatest Common Divisior
We found the divisors of 556, 865, 18, 670 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 556, 865, 18, 670 is 1.
Therefore, GCD of numbers 556, 865, 18, 670 is 1
Given Input Data is 556, 865, 18, 670
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 556 is 2 x 2 x 139
Prime Factorization of 865 is 5 x 173
Prime Factorization of 18 is 2 x 3 x 3
Prime Factorization of 670 is 2 x 5 x 67
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(556, 865) = 480940
GCD(556, 865) = ( 556 x 865 ) / 480940
GCD(556, 865) = 480940 / 480940
GCD(556, 865) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 18
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 18) = 18
GCD(1, 18) = ( 1 x 18 ) / 18
GCD(1, 18) = 18 / 18
GCD(1, 18) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 670
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 670) = 670
GCD(1, 670) = ( 1 x 670 ) / 670
GCD(1, 670) = 670 / 670
GCD(1, 670) = 1
GCD of 556, 865, 18, 670 is 1
