Greatest Common Divisior
We found the divisors of 289, 492, 257, 220 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 289, 492, 257, 220 is 1.
Therefore, GCD of numbers 289, 492, 257, 220 is 1
Given Input Data is 289, 492, 257, 220
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 289 is 17 x 17
Prime Factorization of 492 is 2 x 2 x 3 x 41
Prime Factorization of 257 is 257
Prime Factorization of 220 is 2 x 2 x 5 x 11
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(289, 492) = 142188
GCD(289, 492) = ( 289 x 492 ) / 142188
GCD(289, 492) = 142188 / 142188
GCD(289, 492) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 257
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
GCD(1, 257) = 257 / 257
GCD(1, 257) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 220
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
GCD(1, 220) = 220 / 220
GCD(1, 220) = 1
GCD of 289, 492, 257, 220 is 1
