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 33,129,875, 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 | 33,129,875 | |
| -1 | -33,129,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,129,875.
Example:
1 x 33,129,875 = 33,129,875
and
-1 x -33,129,875 = 33,129,875
Notice both answers equal 33,129,875
With that explanation out of the way, let's continue. Next, we take the number 33,129,875 and divide it by 2:
33,129,875 ÷ 2 = 16,564,937.5
If the quotient is a whole number, then 2 and 16,564,937.5 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 | 33,129,875 | |
| -1 | -33,129,875 |
Now, we try dividing 33,129,875 by 3:
33,129,875 ÷ 3 = 11,043,291.6667
If the quotient is a whole number, then 3 and 11,043,291.6667 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 | 33,129,875 | |
| -1 | -33,129,875 |
Let's try dividing by 4:
33,129,875 ÷ 4 = 8,282,468.75
If the quotient is a whole number, then 4 and 8,282,468.75 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 | 33,129,875 | |
| -1 | 33,129,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 107 | 125 | 535 | 2,477 | 2,675 | 12,385 | 13,375 | 61,925 | 265,039 | 309,625 | 1,325,195 | 6,625,975 | 33,129,875 |
| -1 | -5 | -25 | -107 | -125 | -535 | -2,477 | -2,675 | -12,385 | -13,375 | -61,925 | -265,039 | -309,625 | -1,325,195 | -6,625,975 | -33,129,875 |
