Make use of GCD Calculator to determine the Greatest Common Divisor of 27, 991, 905, 203 i.e. 1 largest integer that divides all the numbers equally.
GCD of 27, 991, 905, 203 is 1
GCD(27, 991, 905, 203) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 27, 991, 905, 203 is 1
GCD(27, 991, 905, 203) = 1
Given Input numbers are 27, 991, 905, 203
To find the GCD of numbers using factoring list out all the divisors of each number

1, 7, 29, 203
Greatest Common Divisior
We found the divisors of 27, 991, 905, 203 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 27, 991, 905, 203 is 1.
Therefore, GCD of numbers 27, 991, 905, 203 is 1
Given Input Data is 27, 991, 905, 203
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 27 is 3 x 3 x 3
Prime Factorization of 991 is 991
Prime Factorization of 905 is 5 x 181
Prime Factorization of 203 is 7 x 29
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(27, 991) = 26757
GCD(27, 991) = ( 27 x 991 ) / 26757
GCD(27, 991) = 26757 / 26757
GCD(27, 991) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 905
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
GCD(1, 905) = 905 / 905
GCD(1, 905) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 203
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 203) = 203
GCD(1, 203) = ( 1 x 203 ) / 203
GCD(1, 203) = 203 / 203
GCD(1, 203) = 1
GCD of 27, 991, 905, 203 is 1
