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 1,331,575, 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 | 1,331,575 | |
| -1 | -1,331,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,331,575.
Example:
1 x 1,331,575 = 1,331,575
and
-1 x -1,331,575 = 1,331,575
Notice both answers equal 1,331,575
With that explanation out of the way, let's continue. Next, we take the number 1,331,575 and divide it by 2:
1,331,575 ÷ 2 = 665,787.5
If the quotient is a whole number, then 2 and 665,787.5 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 | 1,331,575 | |
| -1 | -1,331,575 |
Now, we try dividing 1,331,575 by 3:
1,331,575 ÷ 3 = 443,858.3333
If the quotient is a whole number, then 3 and 443,858.3333 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 | 1,331,575 | |
| -1 | -1,331,575 |
Let's try dividing by 4:
1,331,575 ÷ 4 = 332,893.75
If the quotient is a whole number, then 4 and 332,893.75 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 | 1,331,575 | |
| -1 | 1,331,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,087 | 1,225 | 5,435 | 7,609 | 27,175 | 38,045 | 53,263 | 190,225 | 266,315 | 1,331,575 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,087 | -1,225 | -5,435 | -7,609 | -27,175 | -38,045 | -53,263 | -190,225 | -266,315 | -1,331,575 |
