Greatest Common Divisior
We found the divisors of 251, 989, 12, 457 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 251, 989, 12, 457 is 1.
Therefore, GCD of numbers 251, 989, 12, 457 is 1
Given Input Data is 251, 989, 12, 457
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 251 is 251
Prime Factorization of 989 is 23 x 43
Prime Factorization of 12 is 2 x 2 x 3
Prime Factorization of 457 is 457
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(251, 989) = 248239
GCD(251, 989) = ( 251 x 989 ) / 248239
GCD(251, 989) = 248239 / 248239
GCD(251, 989) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 12
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 12) = 12
GCD(1, 12) = ( 1 x 12 ) / 12
GCD(1, 12) = 12 / 12
GCD(1, 12) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 457
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
GCD(1, 457) = 457 / 457
GCD(1, 457) = 1
GCD of 251, 989, 12, 457 is 1
