Greatest Common Divisior
We found the divisors of 221, 557, 904, 551 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 221, 557, 904, 551 is 1.
Therefore, GCD of numbers 221, 557, 904, 551 is 1
Given Input Data is 221, 557, 904, 551
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 221 is 13 x 17
Prime Factorization of 557 is 557
Prime Factorization of 904 is 2 x 2 x 2 x 113
Prime Factorization of 551 is 19 x 29
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(221, 557) = 123097
GCD(221, 557) = ( 221 x 557 ) / 123097
GCD(221, 557) = 123097 / 123097
GCD(221, 557) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 904
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 904) = 904
GCD(1, 904) = ( 1 x 904 ) / 904
GCD(1, 904) = 904 / 904
GCD(1, 904) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 551
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 551) = 551
GCD(1, 551) = ( 1 x 551 ) / 551
GCD(1, 551) = 551 / 551
GCD(1, 551) = 1
GCD of 221, 557, 904, 551 is 1
