Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 32,010,121, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 32,010,121 | |
| -1 | -32,010,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,010,121.
Example:
1 x 32,010,121 = 32,010,121
and
-1 x -32,010,121 = 32,010,121
Notice both answers equal 32,010,121
With that explanation out of the way, let's continue. Next, we take the number 32,010,121 and divide it by 2:
32,010,121 ÷ 2 = 16,005,060.5
If the quotient is a whole number, then 2 and 16,005,060.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,010,121 | |
| -1 | -32,010,121 |
Now, we try dividing 32,010,121 by 3:
32,010,121 ÷ 3 = 10,670,040.3333
If the quotient is a whole number, then 3 and 10,670,040.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,010,121 | |
| -1 | -32,010,121 |
Let's try dividing by 4:
32,010,121 ÷ 4 = 8,002,530.25
If the quotient is a whole number, then 4 and 8,002,530.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 32,010,121 | |
| -1 | 32,010,121 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 67 | 143 | 169 | 257 | 737 | 871 | 1,859 | 2,827 | 3,341 | 9,581 | 11,323 | 17,219 | 36,751 | 43,433 | 124,553 | 189,409 | 223,847 | 477,763 | 2,462,317 | 2,910,011 | 32,010,121 |
| -1 | -11 | -13 | -67 | -143 | -169 | -257 | -737 | -871 | -1,859 | -2,827 | -3,341 | -9,581 | -11,323 | -17,219 | -36,751 | -43,433 | -124,553 | -189,409 | -223,847 | -477,763 | -2,462,317 | -2,910,011 | -32,010,121 |
