Greatest Common Divisior
We found the divisors of 494, 982, 646, 456 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 494, 982, 646, 456 is 2.
Therefore, GCD of numbers 494, 982, 646, 456 is 2
Given Input Data is 494, 982, 646, 456
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 494 is 2 x 13 x 19
Prime Factorization of 982 is 2 x 491
Prime Factorization of 646 is 2 x 17 x 19
Prime Factorization of 456 is 2 x 2 x 2 x 3 x 19
Highest common occurrences in the given inputs are 21
Multiplying them we get the GCD as 2
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(494, 982) = 242554
GCD(494, 982) = ( 494 x 982 ) / 242554
GCD(494, 982) = 485108 / 242554
GCD(494, 982) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 646
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
GCD(2, 646) = 1292 / 646
GCD(2, 646) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 456
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 456) = 456
GCD(2, 456) = ( 2 x 456 ) / 456
GCD(2, 456) = 912 / 456
GCD(2, 456) = 2
GCD of 494, 982, 646, 456 is 2
