Greatest Common Divisior
We found the divisors of 23, 117, 285, 666 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 23, 117, 285, 666 is 1.
Therefore, GCD of numbers 23, 117, 285, 666 is 1
Given Input Data is 23, 117, 285, 666
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 23 is 23
Prime Factorization of 117 is 3 x 3 x 13
Prime Factorization of 285 is 3 x 5 x 19
Prime Factorization of 666 is 2 x 3 x 3 x 37
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(23, 117) = 2691
GCD(23, 117) = ( 23 x 117 ) / 2691
GCD(23, 117) = 2691 / 2691
GCD(23, 117) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 285
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
GCD(1, 285) = 285 / 285
GCD(1, 285) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 666
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 666) = 666
GCD(1, 666) = ( 1 x 666 ) / 666
GCD(1, 666) = 666 / 666
GCD(1, 666) = 1
GCD of 23, 117, 285, 666 is 1
