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 2,132,225, 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 | 2,132,225 | |
| -1 | -2,132,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,132,225.
Example:
1 x 2,132,225 = 2,132,225
and
-1 x -2,132,225 = 2,132,225
Notice both answers equal 2,132,225
With that explanation out of the way, let's continue. Next, we take the number 2,132,225 and divide it by 2:
2,132,225 ÷ 2 = 1,066,112.5
If the quotient is a whole number, then 2 and 1,066,112.5 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 | 2,132,225 | |
| -1 | -2,132,225 |
Now, we try dividing 2,132,225 by 3:
2,132,225 ÷ 3 = 710,741.6667
If the quotient is a whole number, then 3 and 710,741.6667 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 | 2,132,225 | |
| -1 | -2,132,225 |
Let's try dividing by 4:
2,132,225 ÷ 4 = 533,056.25
If the quotient is a whole number, then 4 and 533,056.25 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 | 2,132,225 | |
| -1 | 2,132,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 29 | 85 | 145 | 173 | 425 | 493 | 725 | 865 | 2,465 | 2,941 | 4,325 | 5,017 | 12,325 | 14,705 | 25,085 | 73,525 | 85,289 | 125,425 | 426,445 | 2,132,225 |
| -1 | -5 | -17 | -25 | -29 | -85 | -145 | -173 | -425 | -493 | -725 | -865 | -2,465 | -2,941 | -4,325 | -5,017 | -12,325 | -14,705 | -25,085 | -73,525 | -85,289 | -125,425 | -426,445 | -2,132,225 |
