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 33,723,515, 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 | 33,723,515 | |
| -1 | -33,723,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,723,515.
Example:
1 x 33,723,515 = 33,723,515
and
-1 x -33,723,515 = 33,723,515
Notice both answers equal 33,723,515
With that explanation out of the way, let's continue. Next, we take the number 33,723,515 and divide it by 2:
33,723,515 ÷ 2 = 16,861,757.5
If the quotient is a whole number, then 2 and 16,861,757.5 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 | 33,723,515 | |
| -1 | -33,723,515 |
Now, we try dividing 33,723,515 by 3:
33,723,515 ÷ 3 = 11,241,171.6667
If the quotient is a whole number, then 3 and 11,241,171.6667 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 | 33,723,515 | |
| -1 | -33,723,515 |
Let's try dividing by 4:
33,723,515 ÷ 4 = 8,430,878.75
If the quotient is a whole number, then 4 and 8,430,878.75 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 | 33,723,515 | |
| -1 | 33,723,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 59 | 245 | 295 | 413 | 2,065 | 2,333 | 2,891 | 11,665 | 14,455 | 16,331 | 81,655 | 114,317 | 137,647 | 571,585 | 688,235 | 963,529 | 4,817,645 | 6,744,703 | 33,723,515 |
| -1 | -5 | -7 | -35 | -49 | -59 | -245 | -295 | -413 | -2,065 | -2,333 | -2,891 | -11,665 | -14,455 | -16,331 | -81,655 | -114,317 | -137,647 | -571,585 | -688,235 | -963,529 | -4,817,645 | -6,744,703 | -33,723,515 |
