Make use of GCD Calculator to determine the Greatest Common Divisor of 490, 447, 27 i.e. 1 largest integer that divides all the numbers equally.
GCD of 490, 447, 27 is 1
GCD(490, 447, 27) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 490, 447, 27 is 1
GCD(490, 447, 27) = 1
Given Input numbers are 490, 447, 27
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 490, 447, 27 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 490, 447, 27 is 1.
Therefore, GCD of numbers 490, 447, 27 is 1
Given Input Data is 490, 447, 27
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 490 is 2 x 5 x 7 x 7
Prime Factorization of 447 is 3 x 149
Prime Factorization of 27 is 3 x 3 x 3
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(490, 447) = 219030
GCD(490, 447) = ( 490 x 447 ) / 219030
GCD(490, 447) = 219030 / 219030
GCD(490, 447) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 27
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 27) = 27
GCD(1, 27) = ( 1 x 27 ) / 27
GCD(1, 27) = 27 / 27
GCD(1, 27) = 1
GCD of 490, 447, 27 is 1
