Greatest Common Divisior
We found the divisors of 287, 919, 68, 123 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 287, 919, 68, 123 is 1.
Therefore, GCD of numbers 287, 919, 68, 123 is 1
Given Input Data is 287, 919, 68, 123
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 287 is 7 x 41
Prime Factorization of 919 is 919
Prime Factorization of 68 is 2 x 2 x 17
Prime Factorization of 123 is 3 x 41
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(287, 919) = 263753
GCD(287, 919) = ( 287 x 919 ) / 263753
GCD(287, 919) = 263753 / 263753
GCD(287, 919) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 68
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 68) = 68
GCD(1, 68) = ( 1 x 68 ) / 68
GCD(1, 68) = 68 / 68
GCD(1, 68) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 123
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
GCD(1, 123) = 123 / 123
GCD(1, 123) = 1
GCD of 287, 919, 68, 123 is 1
