Greatest Common Divisior
We found the divisors of 578, 790, 99, 285 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 578, 790, 99, 285 is 1.
Therefore, GCD of numbers 578, 790, 99, 285 is 1
Given Input Data is 578, 790, 99, 285
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 578 is 2 x 17 x 17
Prime Factorization of 790 is 2 x 5 x 79
Prime Factorization of 99 is 3 x 3 x 11
Prime Factorization of 285 is 3 x 5 x 19
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(578, 790) = 228310
GCD(578, 790) = ( 578 x 790 ) / 228310
GCD(578, 790) = 456620 / 228310
GCD(578, 790) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 99
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 99) = 198
GCD(2, 99) = ( 2 x 99 ) / 198
GCD(2, 99) = 198 / 198
GCD(2, 99) = 1
Step3:
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
GCD of 578, 790, 99, 285 is 1
