Greatest Common Divisior
We found the divisors of 571, 455, 561, 193 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 571, 455, 561, 193 is 1.
Therefore, GCD of numbers 571, 455, 561, 193 is 1
Given Input Data is 571, 455, 561, 193
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 571 is 571
Prime Factorization of 455 is 5 x 7 x 13
Prime Factorization of 561 is 3 x 11 x 17
Prime Factorization of 193 is 193
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(571, 455) = 259805
GCD(571, 455) = ( 571 x 455 ) / 259805
GCD(571, 455) = 259805 / 259805
GCD(571, 455) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 561
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
GCD(1, 561) = 561 / 561
GCD(1, 561) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 193
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 193) = 193
GCD(1, 193) = ( 1 x 193 ) / 193
GCD(1, 193) = 193 / 193
GCD(1, 193) = 1
GCD of 571, 455, 561, 193 is 1
