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 1,329,251, 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 | 1,329,251 | |
| -1 | -1,329,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,329,251.
Example:
1 x 1,329,251 = 1,329,251
and
-1 x -1,329,251 = 1,329,251
Notice both answers equal 1,329,251
With that explanation out of the way, let's continue. Next, we take the number 1,329,251 and divide it by 2:
1,329,251 ÷ 2 = 664,625.5
If the quotient is a whole number, then 2 and 664,625.5 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 | 1,329,251 | |
| -1 | -1,329,251 |
Now, we try dividing 1,329,251 by 3:
1,329,251 ÷ 3 = 443,083.6667
If the quotient is a whole number, then 3 and 443,083.6667 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 | 1,329,251 | |
| -1 | -1,329,251 |
Let's try dividing by 4:
1,329,251 ÷ 4 = 332,312.75
If the quotient is a whole number, then 4 and 332,312.75 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 | 1,329,251 | |
| -1 | 1,329,251 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 61 | 77 | 283 | 427 | 671 | 1,981 | 3,113 | 4,697 | 17,263 | 21,791 | 120,841 | 189,893 | 1,329,251 |
| -1 | -7 | -11 | -61 | -77 | -283 | -427 | -671 | -1,981 | -3,113 | -4,697 | -17,263 | -21,791 | -120,841 | -189,893 | -1,329,251 |
