Greatest Common Divisior
We found the divisors of 664, 698, 490 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 664, 698, 490 is 2.
Therefore, GCD of numbers 664, 698, 490 is 2
Given Input Data is 664, 698, 490
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 664 is 2 x 2 x 2 x 83
Prime Factorization of 698 is 2 x 349
Prime Factorization of 490 is 2 x 5 x 7 x 7
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(664, 698) = 231736
GCD(664, 698) = ( 664 x 698 ) / 231736
GCD(664, 698) = 463472 / 231736
GCD(664, 698) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 490
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 490) = 490
GCD(2, 490) = ( 2 x 490 ) / 490
GCD(2, 490) = 980 / 490
GCD(2, 490) = 2
GCD of 664, 698, 490 is 2
