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 33,684,415, 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 | 33,684,415 | |
| -1 | -33,684,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,684,415.
Example:
1 x 33,684,415 = 33,684,415
and
-1 x -33,684,415 = 33,684,415
Notice both answers equal 33,684,415
With that explanation out of the way, let's continue. Next, we take the number 33,684,415 and divide it by 2:
33,684,415 ÷ 2 = 16,842,207.5
If the quotient is a whole number, then 2 and 16,842,207.5 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 | 33,684,415 | |
| -1 | -33,684,415 |
Now, we try dividing 33,684,415 by 3:
33,684,415 ÷ 3 = 11,228,138.3333
If the quotient is a whole number, then 3 and 11,228,138.3333 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 | 33,684,415 | |
| -1 | -33,684,415 |
Let's try dividing by 4:
33,684,415 ÷ 4 = 8,421,103.75
If the quotient is a whole number, then 4 and 8,421,103.75 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 | 33,684,415 | |
| -1 | 33,684,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 79 | 265 | 395 | 1,609 | 4,187 | 8,045 | 20,935 | 85,277 | 127,111 | 426,385 | 635,555 | 6,736,883 | 33,684,415 |
| -1 | -5 | -53 | -79 | -265 | -395 | -1,609 | -4,187 | -8,045 | -20,935 | -85,277 | -127,111 | -426,385 | -635,555 | -6,736,883 | -33,684,415 |
