Make use of GCD Calculator to determine the Greatest Common Divisor of 984, 393, 91, 641 i.e. 1 largest integer that divides all the numbers equally.
GCD of 984, 393, 91, 641 is 1
GCD(984, 393, 91, 641) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 984, 393, 91, 641 is 1
GCD(984, 393, 91, 641) = 1
Given Input numbers are 984, 393, 91, 641
To find the GCD of numbers using factoring list out all the divisors of each number

1, 641
Greatest Common Divisior
We found the divisors of 984, 393, 91, 641 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 984, 393, 91, 641 is 1.
Therefore, GCD of numbers 984, 393, 91, 641 is 1
Given Input Data is 984, 393, 91, 641
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 984 is 2 x 2 x 2 x 3 x 41
Prime Factorization of 393 is 3 x 131
Prime Factorization of 91 is 7 x 13
Prime Factorization of 641 is 641
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(984, 393) = 128904
GCD(984, 393) = ( 984 x 393 ) / 128904
GCD(984, 393) = 386712 / 128904
GCD(984, 393) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 91
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 91) = 273
GCD(3, 91) = ( 3 x 91 ) / 273
GCD(3, 91) = 273 / 273
GCD(3, 91) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 641
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
GCD(1, 641) = 641 / 641
GCD(1, 641) = 1
GCD of 984, 393, 91, 641 is 1
