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 33,442,315, 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 | 33,442,315 | |
| -1 | -33,442,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,442,315.
Example:
1 x 33,442,315 = 33,442,315
and
-1 x -33,442,315 = 33,442,315
Notice both answers equal 33,442,315
With that explanation out of the way, let's continue. Next, we take the number 33,442,315 and divide it by 2:
33,442,315 ÷ 2 = 16,721,157.5
If the quotient is a whole number, then 2 and 16,721,157.5 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 | 33,442,315 | |
| -1 | -33,442,315 |
Now, we try dividing 33,442,315 by 3:
33,442,315 ÷ 3 = 11,147,438.3333
If the quotient is a whole number, then 3 and 11,147,438.3333 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 | 33,442,315 | |
| -1 | -33,442,315 |
Let's try dividing by 4:
33,442,315 ÷ 4 = 8,360,578.75
If the quotient is a whole number, then 4 and 8,360,578.75 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 | 33,442,315 | |
| -1 | 33,442,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 107 | 535 | 1,819 | 3,677 | 9,095 | 18,385 | 62,509 | 312,545 | 393,439 | 1,967,195 | 6,688,463 | 33,442,315 |
| -1 | -5 | -17 | -85 | -107 | -535 | -1,819 | -3,677 | -9,095 | -18,385 | -62,509 | -312,545 | -393,439 | -1,967,195 | -6,688,463 | -33,442,315 |
