Greatest Common Divisior
We found the divisors of 291, 997, 20, 568 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 291, 997, 20, 568 is 1.
Therefore, GCD of numbers 291, 997, 20, 568 is 1
Given Input Data is 291, 997, 20, 568
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 291 is 3 x 97
Prime Factorization of 997 is 997
Prime Factorization of 20 is 2 x 2 x 5
Prime Factorization of 568 is 2 x 2 x 2 x 71
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(291, 997) = 290127
GCD(291, 997) = ( 291 x 997 ) / 290127
GCD(291, 997) = 290127 / 290127
GCD(291, 997) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 20
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
GCD(1, 20) = 20 / 20
GCD(1, 20) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 568
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 568) = 568
GCD(1, 568) = ( 1 x 568 ) / 568
GCD(1, 568) = 568 / 568
GCD(1, 568) = 1
GCD of 291, 997, 20, 568 is 1
