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 2,133,875, 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 | 2,133,875 | |
| -1 | -2,133,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,133,875.
Example:
1 x 2,133,875 = 2,133,875
and
-1 x -2,133,875 = 2,133,875
Notice both answers equal 2,133,875
With that explanation out of the way, let's continue. Next, we take the number 2,133,875 and divide it by 2:
2,133,875 ÷ 2 = 1,066,937.5
If the quotient is a whole number, then 2 and 1,066,937.5 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 | 2,133,875 | |
| -1 | -2,133,875 |
Now, we try dividing 2,133,875 by 3:
2,133,875 ÷ 3 = 711,291.6667
If the quotient is a whole number, then 3 and 711,291.6667 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 | 2,133,875 | |
| -1 | -2,133,875 |
Let's try dividing by 4:
2,133,875 ÷ 4 = 533,468.75
If the quotient is a whole number, then 4 and 533,468.75 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 | 2,133,875 | |
| -1 | 2,133,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 125 | 215 | 397 | 1,075 | 1,985 | 5,375 | 9,925 | 17,071 | 49,625 | 85,355 | 426,775 | 2,133,875 |
| -1 | -5 | -25 | -43 | -125 | -215 | -397 | -1,075 | -1,985 | -5,375 | -9,925 | -17,071 | -49,625 | -85,355 | -426,775 | -2,133,875 |
