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 2,438,755, 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 | 2,438,755 | |
| -1 | -2,438,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,438,755.
Example:
1 x 2,438,755 = 2,438,755
and
-1 x -2,438,755 = 2,438,755
Notice both answers equal 2,438,755
With that explanation out of the way, let's continue. Next, we take the number 2,438,755 and divide it by 2:
2,438,755 ÷ 2 = 1,219,377.5
If the quotient is a whole number, then 2 and 1,219,377.5 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 | 2,438,755 | |
| -1 | -2,438,755 |
Now, we try dividing 2,438,755 by 3:
2,438,755 ÷ 3 = 812,918.3333
If the quotient is a whole number, then 3 and 812,918.3333 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 | 2,438,755 | |
| -1 | -2,438,755 |
Let's try dividing by 4:
2,438,755 ÷ 4 = 609,688.75
If the quotient is a whole number, then 4 and 609,688.75 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 | 2,438,755 | |
| -1 | 2,438,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 121 | 139 | 145 | 319 | 605 | 695 | 1,529 | 1,595 | 3,509 | 4,031 | 7,645 | 16,819 | 17,545 | 20,155 | 44,341 | 84,095 | 221,705 | 487,751 | 2,438,755 |
| -1 | -5 | -11 | -29 | -55 | -121 | -139 | -145 | -319 | -605 | -695 | -1,529 | -1,595 | -3,509 | -4,031 | -7,645 | -16,819 | -17,545 | -20,155 | -44,341 | -84,095 | -221,705 | -487,751 | -2,438,755 |
