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 32,913,173, 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 | 32,913,173 | |
| -1 | -32,913,173 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,913,173.
Example:
1 x 32,913,173 = 32,913,173
and
-1 x -32,913,173 = 32,913,173
Notice both answers equal 32,913,173
With that explanation out of the way, let's continue. Next, we take the number 32,913,173 and divide it by 2:
32,913,173 ÷ 2 = 16,456,586.5
If the quotient is a whole number, then 2 and 16,456,586.5 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 | 32,913,173 | |
| -1 | -32,913,173 |
Now, we try dividing 32,913,173 by 3:
32,913,173 ÷ 3 = 10,971,057.6667
If the quotient is a whole number, then 3 and 10,971,057.6667 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 | 32,913,173 | |
| -1 | -32,913,173 |
Let's try dividing by 4:
32,913,173 ÷ 4 = 8,228,293.25
If the quotient is a whole number, then 4 and 8,228,293.25 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 | 32,913,173 | |
| -1 | 32,913,173 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 101 | 493 | 661 | 1,717 | 2,929 | 11,237 | 19,169 | 49,793 | 66,761 | 325,873 | 1,134,937 | 1,936,069 | 32,913,173 |
| -1 | -17 | -29 | -101 | -493 | -661 | -1,717 | -2,929 | -11,237 | -19,169 | -49,793 | -66,761 | -325,873 | -1,134,937 | -1,936,069 | -32,913,173 |
