Make use of GCD Calculator to determine the Greatest Common Divisor of 401, 470, 389, 905 i.e. 1 largest integer that divides all the numbers equally.
GCD of 401, 470, 389, 905 is 1
GCD(401, 470, 389, 905) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 401, 470, 389, 905 is 1
GCD(401, 470, 389, 905) = 1
Given Input numbers are 401, 470, 389, 905
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 401
List of positive integer divisors of 401 that divides 401 without a remainder.
1, 401
Divisors of 470

1, 2, 5, 10, 47, 94, 235, 470
Divisors of 389
List of positive integer divisors of 389 that divides 389 without a remainder.
1, 389
Divisors of 905
List of positive integer divisors of 905 that divides 905 without a remainder.
1, 5, 181, 905
Greatest Common Divisior
We found the divisors of 401, 470, 389, 905 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 401, 470, 389, 905 is 1.
Therefore, GCD of numbers 401, 470, 389, 905 is 1
Given Input Data is 401, 470, 389, 905
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 401 is 401
Prime Factorization of 470 is 2 x 5 x 47
Prime Factorization of 389 is 389
Prime Factorization of 905 is 5 x 181
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(401, 470) = 188470
GCD(401, 470) = ( 401 x 470 ) / 188470
GCD(401, 470) = 188470 / 188470
GCD(401, 470) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 389
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
GCD(1, 389) = 389 / 389
GCD(1, 389) = 1
Step3:
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
GCD of 401, 470, 389, 905 is 1
