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 33,331,319, 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 | 33,331,319 | |
| -1 | -33,331,319 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,331,319.
Example:
1 x 33,331,319 = 33,331,319
and
-1 x -33,331,319 = 33,331,319
Notice both answers equal 33,331,319
With that explanation out of the way, let's continue. Next, we take the number 33,331,319 and divide it by 2:
33,331,319 ÷ 2 = 16,665,659.5
If the quotient is a whole number, then 2 and 16,665,659.5 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 | 33,331,319 | |
| -1 | -33,331,319 |
Now, we try dividing 33,331,319 by 3:
33,331,319 ÷ 3 = 11,110,439.6667
If the quotient is a whole number, then 3 and 11,110,439.6667 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 | 33,331,319 | |
| -1 | -33,331,319 |
Let's try dividing by 4:
33,331,319 ÷ 4 = 8,332,829.75
If the quotient is a whole number, then 4 and 8,332,829.75 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 | 33,331,319 | |
| -1 | 33,331,319 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 47 | 49 | 287 | 329 | 353 | 1,927 | 2,009 | 2,303 | 2,471 | 13,489 | 14,473 | 16,591 | 17,297 | 94,423 | 101,311 | 116,137 | 680,231 | 709,177 | 812,959 | 4,761,617 | 33,331,319 |
| -1 | -7 | -41 | -47 | -49 | -287 | -329 | -353 | -1,927 | -2,009 | -2,303 | -2,471 | -13,489 | -14,473 | -16,591 | -17,297 | -94,423 | -101,311 | -116,137 | -680,231 | -709,177 | -812,959 | -4,761,617 | -33,331,319 |
