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 1,338,755, 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 | 1,338,755 | |
| -1 | -1,338,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,338,755.
Example:
1 x 1,338,755 = 1,338,755
and
-1 x -1,338,755 = 1,338,755
Notice both answers equal 1,338,755
With that explanation out of the way, let's continue. Next, we take the number 1,338,755 and divide it by 2:
1,338,755 ÷ 2 = 669,377.5
If the quotient is a whole number, then 2 and 669,377.5 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 | 1,338,755 | |
| -1 | -1,338,755 |
Now, we try dividing 1,338,755 by 3:
1,338,755 ÷ 3 = 446,251.6667
If the quotient is a whole number, then 3 and 446,251.6667 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 | 1,338,755 | |
| -1 | -1,338,755 |
Let's try dividing by 4:
1,338,755 ÷ 4 = 334,688.75
If the quotient is a whole number, then 4 and 334,688.75 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 | 1,338,755 | |
| -1 | 1,338,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 101 | 241 | 505 | 1,111 | 1,205 | 2,651 | 5,555 | 13,255 | 24,341 | 121,705 | 267,751 | 1,338,755 |
| -1 | -5 | -11 | -55 | -101 | -241 | -505 | -1,111 | -1,205 | -2,651 | -5,555 | -13,255 | -24,341 | -121,705 | -267,751 | -1,338,755 |
