1, 2, 449, 898
Greatest Common Divisior
We found the divisors of 487, 257, 243, 898 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 487, 257, 243, 898 is 1.
Therefore, GCD of numbers 487, 257, 243, 898 is 1
Given Input Data is 487, 257, 243, 898
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 487 is 487
Prime Factorization of 257 is 257
Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3
Prime Factorization of 898 is 2 x 449
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(487, 257) = 125159
GCD(487, 257) = ( 487 x 257 ) / 125159
GCD(487, 257) = 125159 / 125159
GCD(487, 257) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 243
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 243) = 243
GCD(1, 243) = ( 1 x 243 ) / 243
GCD(1, 243) = 243 / 243
GCD(1, 243) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 898
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 898) = 898
GCD(1, 898) = ( 1 x 898 ) / 898
GCD(1, 898) = 898 / 898
GCD(1, 898) = 1
GCD of 487, 257, 243, 898 is 1
