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 33,489,287, 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 | 33,489,287 | |
| -1 | -33,489,287 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,489,287.
Example:
1 x 33,489,287 = 33,489,287
and
-1 x -33,489,287 = 33,489,287
Notice both answers equal 33,489,287
With that explanation out of the way, let's continue. Next, we take the number 33,489,287 and divide it by 2:
33,489,287 ÷ 2 = 16,744,643.5
If the quotient is a whole number, then 2 and 16,744,643.5 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 | 33,489,287 | |
| -1 | -33,489,287 |
Now, we try dividing 33,489,287 by 3:
33,489,287 ÷ 3 = 11,163,095.6667
If the quotient is a whole number, then 3 and 11,163,095.6667 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 | 33,489,287 | |
| -1 | -33,489,287 |
Let's try dividing by 4:
33,489,287 ÷ 4 = 8,372,321.75
If the quotient is a whole number, then 4 and 8,372,321.75 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 | 33,489,287 | |
| -1 | 33,489,287 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 211 | 377 | 421 | 2,743 | 5,473 | 6,119 | 12,209 | 79,547 | 88,831 | 158,717 | 1,154,803 | 2,576,099 | 33,489,287 |
| -1 | -13 | -29 | -211 | -377 | -421 | -2,743 | -5,473 | -6,119 | -12,209 | -79,547 | -88,831 | -158,717 | -1,154,803 | -2,576,099 | -33,489,287 |
