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 2,088,725, 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 | 2,088,725 | |
| -1 | -2,088,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,088,725.
Example:
1 x 2,088,725 = 2,088,725
and
-1 x -2,088,725 = 2,088,725
Notice both answers equal 2,088,725
With that explanation out of the way, let's continue. Next, we take the number 2,088,725 and divide it by 2:
2,088,725 ÷ 2 = 1,044,362.5
If the quotient is a whole number, then 2 and 1,044,362.5 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 | 2,088,725 | |
| -1 | -2,088,725 |
Now, we try dividing 2,088,725 by 3:
2,088,725 ÷ 3 = 696,241.6667
If the quotient is a whole number, then 3 and 696,241.6667 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 | 2,088,725 | |
| -1 | -2,088,725 |
Let's try dividing by 4:
2,088,725 ÷ 4 = 522,181.25
If the quotient is a whole number, then 4 and 522,181.25 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 | 2,088,725 | |
| -1 | 2,088,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 43 | 67 | 145 | 215 | 335 | 725 | 1,075 | 1,247 | 1,675 | 1,943 | 2,881 | 6,235 | 9,715 | 14,405 | 31,175 | 48,575 | 72,025 | 83,549 | 417,745 | 2,088,725 |
| -1 | -5 | -25 | -29 | -43 | -67 | -145 | -215 | -335 | -725 | -1,075 | -1,247 | -1,675 | -1,943 | -2,881 | -6,235 | -9,715 | -14,405 | -31,175 | -48,575 | -72,025 | -83,549 | -417,745 | -2,088,725 |
