Which divisors to find?
Calculate absolutely all factors. (Including 1 and the number itself.)
Calculate only proper divisors. (Excluding the number itself.)
Calculate proper divisors but exclude value '1'.
Divisors Separator
Separate divisors by this symbol.
Divisors calculator tool What is a divisors calculator?
This tool calculates all divisors of the given number. An integer x is called a divisor (or a factor) of the number n if dividing n by x leaves no reminder. For example, for the number 6, the divisors are 1, 2, 3, 6, and for the number 7 only: 1, 7 (because it is a prime number). With this tool you can instantly find all factors of a number (including one and number itself), or you can get proper factors (which is all divisors without the number itself). You can also calculate factors of several values at once by writing each value on a new line. And to make output more flexible you can also set the symbol that will be inserted between all factors. Mathabulous!

Find All Integers that Divide Number 500
In this example we find all divisors of the integer 500 and separate them all with a comma.
500
1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500

Calculate absolutely all factors. (Including 1 and the number itself.)
Separate divisors by this symbol.
Proper Divisors of Three Consecutive Numbers
This example calculates proper factors of three consecutive integers 100, 101 and 102. The number 101 is a prime number (that is, divisible only by itself and by 1), and as we're only interested in proper divisors, in the second line we get only one divisor: 1.
100 101 102
1; 2; 4; 5; 10; 20; 25; 50 1 1; 2; 3; 6; 17; 34; 51

Separate divisors by this symbol.
Powers of 2
In this example we find divisors of the integer 1048575, which is 2^20 (two raised to power 20). All divisors of this number are different powers of the number 2, starting from zeroth power to twentieth power.
1048576
1 2 4 8 16 32 64 128 256 512 1024 2048 4096 8192 16384 32768 65536 131072 262144 524288 1048576
