Make use of GCD Calculator to determine the Greatest Common Divisor of 69, 394, 449, 169 i.e. 1 largest integer that divides all the numbers equally.
GCD of 69, 394, 449, 169 is 1
GCD(69, 394, 449, 169) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 69, 394, 449, 169 is 1
GCD(69, 394, 449, 169) = 1
Given Input numbers are 69, 394, 449, 169
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 69, 394, 449, 169 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 69, 394, 449, 169 is 1.
Therefore, GCD of numbers 69, 394, 449, 169 is 1
Given Input Data is 69, 394, 449, 169
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 69 is 3 x 23
Prime Factorization of 394 is 2 x 197
Prime Factorization of 449 is 449
Prime Factorization of 169 is 13 x 13
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(69, 394) = 27186
GCD(69, 394) = ( 69 x 394 ) / 27186
GCD(69, 394) = 27186 / 27186
GCD(69, 394) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 449
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
GCD(1, 449) = 449 / 449
GCD(1, 449) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 169
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 169) = 169
GCD(1, 169) = ( 1 x 169 ) / 169
GCD(1, 169) = 169 / 169
GCD(1, 169) = 1
GCD of 69, 394, 449, 169 is 1
