Make use of GCD Calculator to determine the Greatest Common Divisor of 41, 397, 445, 646 i.e. 1 largest integer that divides all the numbers equally.
GCD of 41, 397, 445, 646 is 1
GCD(41, 397, 445, 646) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 41, 397, 445, 646 is 1
GCD(41, 397, 445, 646) = 1
Given Input numbers are 41, 397, 445, 646
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 41, 397, 445, 646 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 41, 397, 445, 646 is 1.
Therefore, GCD of numbers 41, 397, 445, 646 is 1
Given Input Data is 41, 397, 445, 646
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 41 is 41
Prime Factorization of 397 is 397
Prime Factorization of 445 is 5 x 89
Prime Factorization of 646 is 2 x 17 x 19
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(41, 397) = 16277
GCD(41, 397) = ( 41 x 397 ) / 16277
GCD(41, 397) = 16277 / 16277
GCD(41, 397) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 445
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
GCD(1, 445) = 445 / 445
GCD(1, 445) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 646
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
GCD(1, 646) = 646 / 646
GCD(1, 646) = 1
GCD of 41, 397, 445, 646 is 1
