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 32,131,043, 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 | 32,131,043 | |
| -1 | -32,131,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,131,043.
Example:
1 x 32,131,043 = 32,131,043
and
-1 x -32,131,043 = 32,131,043
Notice both answers equal 32,131,043
With that explanation out of the way, let's continue. Next, we take the number 32,131,043 and divide it by 2:
32,131,043 ÷ 2 = 16,065,521.5
If the quotient is a whole number, then 2 and 16,065,521.5 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 | 32,131,043 | |
| -1 | -32,131,043 |
Now, we try dividing 32,131,043 by 3:
32,131,043 ÷ 3 = 10,710,347.6667
If the quotient is a whole number, then 3 and 10,710,347.6667 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 | 32,131,043 | |
| -1 | -32,131,043 |
Let's try dividing by 4:
32,131,043 ÷ 4 = 8,032,760.75
If the quotient is a whole number, then 4 and 8,032,760.75 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 | 32,131,043 | |
| -1 | 32,131,043 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 83 | 203 | 581 | 1,907 | 2,407 | 13,349 | 16,849 | 55,303 | 158,281 | 387,121 | 1,107,967 | 4,590,149 | 32,131,043 |
| -1 | -7 | -29 | -83 | -203 | -581 | -1,907 | -2,407 | -13,349 | -16,849 | -55,303 | -158,281 | -387,121 | -1,107,967 | -4,590,149 | -32,131,043 |
