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 1,392,365, 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 | 1,392,365 | |
| -1 | -1,392,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,392,365.
Example:
1 x 1,392,365 = 1,392,365
and
-1 x -1,392,365 = 1,392,365
Notice both answers equal 1,392,365
With that explanation out of the way, let's continue. Next, we take the number 1,392,365 and divide it by 2:
1,392,365 ÷ 2 = 696,182.5
If the quotient is a whole number, then 2 and 696,182.5 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 | 1,392,365 | |
| -1 | -1,392,365 |
Now, we try dividing 1,392,365 by 3:
1,392,365 ÷ 3 = 464,121.6667
If the quotient is a whole number, then 3 and 464,121.6667 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 | 1,392,365 | |
| -1 | -1,392,365 |
Let's try dividing by 4:
1,392,365 ÷ 4 = 348,091.25
If the quotient is a whole number, then 4 and 348,091.25 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 | 1,392,365 | |
| -1 | 1,392,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 31 | 65 | 155 | 403 | 691 | 2,015 | 3,455 | 8,983 | 21,421 | 44,915 | 107,105 | 278,473 | 1,392,365 |
| -1 | -5 | -13 | -31 | -65 | -155 | -403 | -691 | -2,015 | -3,455 | -8,983 | -21,421 | -44,915 | -107,105 | -278,473 | -1,392,365 |
