Make use of GCD Calculator to determine the Greatest Common Divisor of 921, 905, 19, 827 i.e. 1 largest integer that divides all the numbers equally.
GCD of 921, 905, 19, 827 is 1
GCD(921, 905, 19, 827) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 921, 905, 19, 827 is 1
GCD(921, 905, 19, 827) = 1
Given Input numbers are 921, 905, 19, 827
To find the GCD of numbers using factoring list out all the divisors of each number

1, 827
Greatest Common Divisior
We found the divisors of 921, 905, 19, 827 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 921, 905, 19, 827 is 1.
Therefore, GCD of numbers 921, 905, 19, 827 is 1
Given Input Data is 921, 905, 19, 827
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 921 is 3 x 307
Prime Factorization of 905 is 5 x 181
Prime Factorization of 19 is 19
Prime Factorization of 827 is 827
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(921, 905) = 833505
GCD(921, 905) = ( 921 x 905 ) / 833505
GCD(921, 905) = 833505 / 833505
GCD(921, 905) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 19
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 19) = 19
GCD(1, 19) = ( 1 x 19 ) / 19
GCD(1, 19) = 19 / 19
GCD(1, 19) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 827
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 827) = 827
GCD(1, 827) = ( 1 x 827 ) / 827
GCD(1, 827) = 827 / 827
GCD(1, 827) = 1
GCD of 921, 905, 19, 827 is 1
