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 518,795, 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 | 518,795 | |
| -1 | -518,795 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 518,795.
Example:
1 x 518,795 = 518,795
and
-1 x -518,795 = 518,795
Notice both answers equal 518,795
With that explanation out of the way, let's continue. Next, we take the number 518,795 and divide it by 2:
518,795 ÷ 2 = 259,397.5
If the quotient is a whole number, then 2 and 259,397.5 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 | 518,795 | |
| -1 | -518,795 |
Now, we try dividing 518,795 by 3:
518,795 ÷ 3 = 172,931.6667
If the quotient is a whole number, then 3 and 172,931.6667 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 | 518,795 | |
| -1 | -518,795 |
Let's try dividing by 4:
518,795 ÷ 4 = 129,698.75
If the quotient is a whole number, then 4 and 129,698.75 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 | 518,795 | |
| -1 | 518,795 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 43 | 95 | 127 | 215 | 635 | 817 | 2,413 | 4,085 | 5,461 | 12,065 | 27,305 | 103,759 | 518,795 |
| -1 | -5 | -19 | -43 | -95 | -127 | -215 | -635 | -817 | -2,413 | -4,085 | -5,461 | -12,065 | -27,305 | -103,759 | -518,795 |
