Make use of GCD Calculator to determine the Greatest Common Divisor of 449, 254, 28, 717 i.e. 1 largest integer that divides all the numbers equally.
GCD of 449, 254, 28, 717 is 1
GCD(449, 254, 28, 717) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 449, 254, 28, 717 is 1
GCD(449, 254, 28, 717) = 1
Given Input numbers are 449, 254, 28, 717
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 239, 717
Greatest Common Divisior
We found the divisors of 449, 254, 28, 717 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 449, 254, 28, 717 is 1.
Therefore, GCD of numbers 449, 254, 28, 717 is 1
Given Input Data is 449, 254, 28, 717
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 449 is 449
Prime Factorization of 254 is 2 x 127
Prime Factorization of 28 is 2 x 2 x 7
Prime Factorization of 717 is 3 x 239
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(449, 254) = 114046
GCD(449, 254) = ( 449 x 254 ) / 114046
GCD(449, 254) = 114046 / 114046
GCD(449, 254) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 28
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 28) = 28
GCD(1, 28) = ( 1 x 28 ) / 28
GCD(1, 28) = 28 / 28
GCD(1, 28) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 717
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 717) = 717
GCD(1, 717) = ( 1 x 717 ) / 717
GCD(1, 717) = 717 / 717
GCD(1, 717) = 1
GCD of 449, 254, 28, 717 is 1
