Make use of GCD Calculator to determine the Greatest Common Divisor of 397, 549, 60, 449 i.e. 1 largest integer that divides all the numbers equally.
GCD of 397, 549, 60, 449 is 1
GCD(397, 549, 60, 449) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 397, 549, 60, 449 is 1
GCD(397, 549, 60, 449) = 1
Given Input numbers are 397, 549, 60, 449
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 397

1, 449
Greatest Common Divisior
We found the divisors of 397, 549, 60, 449 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 397, 549, 60, 449 is 1.
Therefore, GCD of numbers 397, 549, 60, 449 is 1
Given Input Data is 397, 549, 60, 449
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 397 is 397
Prime Factorization of 549 is 3 x 3 x 61
Prime Factorization of 60 is 2 x 2 x 3 x 5
Prime Factorization of 449 is 449
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(397, 549) = 217953
GCD(397, 549) = ( 397 x 549 ) / 217953
GCD(397, 549) = 217953 / 217953
GCD(397, 549) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 60
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 60) = 60
GCD(1, 60) = ( 1 x 60 ) / 60
GCD(1, 60) = 60 / 60
GCD(1, 60) = 1
Step3:
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
GCD of 397, 549, 60, 449 is 1
