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 31,500,833, 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 | 31,500,833 | |
| -1 | -31,500,833 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,500,833.
Example:
1 x 31,500,833 = 31,500,833
and
-1 x -31,500,833 = 31,500,833
Notice both answers equal 31,500,833
With that explanation out of the way, let's continue. Next, we take the number 31,500,833 and divide it by 2:
31,500,833 ÷ 2 = 15,750,416.5
If the quotient is a whole number, then 2 and 15,750,416.5 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 | 31,500,833 | |
| -1 | -31,500,833 |
Now, we try dividing 31,500,833 by 3:
31,500,833 ÷ 3 = 10,500,277.6667
If the quotient is a whole number, then 3 and 10,500,277.6667 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 | 31,500,833 | |
| -1 | -31,500,833 |
Let's try dividing by 4:
31,500,833 ÷ 4 = 7,875,208.25
If the quotient is a whole number, then 4 and 7,875,208.25 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 | 31,500,833 | |
| -1 | 31,500,833 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 41 | 91 | 287 | 533 | 3,731 | 8,443 | 59,101 | 109,759 | 346,163 | 768,313 | 2,423,141 | 4,500,119 | 31,500,833 |
| -1 | -7 | -13 | -41 | -91 | -287 | -533 | -3,731 | -8,443 | -59,101 | -109,759 | -346,163 | -768,313 | -2,423,141 | -4,500,119 | -31,500,833 |
