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 1,358,291, 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 | 1,358,291 | |
| -1 | -1,358,291 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,358,291.
Example:
1 x 1,358,291 = 1,358,291
and
-1 x -1,358,291 = 1,358,291
Notice both answers equal 1,358,291
With that explanation out of the way, let's continue. Next, we take the number 1,358,291 and divide it by 2:
1,358,291 ÷ 2 = 679,145.5
If the quotient is a whole number, then 2 and 679,145.5 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 | 1,358,291 | |
| -1 | -1,358,291 |
Now, we try dividing 1,358,291 by 3:
1,358,291 ÷ 3 = 452,763.6667
If the quotient is a whole number, then 3 and 452,763.6667 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 | 1,358,291 | |
| -1 | -1,358,291 |
Let's try dividing by 4:
1,358,291 ÷ 4 = 339,572.75
If the quotient is a whole number, then 4 and 339,572.75 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 | 1,358,291 | |
| -1 | 1,358,291 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 67 | 97 | 209 | 737 | 1,067 | 1,273 | 1,843 | 6,499 | 14,003 | 20,273 | 71,489 | 123,481 | 1,358,291 |
| -1 | -11 | -19 | -67 | -97 | -209 | -737 | -1,067 | -1,273 | -1,843 | -6,499 | -14,003 | -20,273 | -71,489 | -123,481 | -1,358,291 |
