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 1,386,707, 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 | 1,386,707 | |
| -1 | -1,386,707 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,386,707.
Example:
1 x 1,386,707 = 1,386,707
and
-1 x -1,386,707 = 1,386,707
Notice both answers equal 1,386,707
With that explanation out of the way, let's continue. Next, we take the number 1,386,707 and divide it by 2:
1,386,707 ÷ 2 = 693,353.5
If the quotient is a whole number, then 2 and 693,353.5 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 | 1,386,707 | |
| -1 | -1,386,707 |
Now, we try dividing 1,386,707 by 3:
1,386,707 ÷ 3 = 462,235.6667
If the quotient is a whole number, then 3 and 462,235.6667 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 | 1,386,707 | |
| -1 | -1,386,707 |
Let's try dividing by 4:
1,386,707 ÷ 4 = 346,676.75
If the quotient is a whole number, then 4 and 346,676.75 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 | 1,386,707 | |
| -1 | 1,386,707 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 43 | 119 | 271 | 301 | 731 | 1,897 | 4,607 | 5,117 | 11,653 | 32,249 | 81,571 | 198,101 | 1,386,707 |
| -1 | -7 | -17 | -43 | -119 | -271 | -301 | -731 | -1,897 | -4,607 | -5,117 | -11,653 | -32,249 | -81,571 | -198,101 | -1,386,707 |
