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 285,775, 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 | 285,775 | |
| -1 | -285,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 285,775.
Example:
1 x 285,775 = 285,775
and
-1 x -285,775 = 285,775
Notice both answers equal 285,775
With that explanation out of the way, let's continue. Next, we take the number 285,775 and divide it by 2:
285,775 ÷ 2 = 142,887.5
If the quotient is a whole number, then 2 and 142,887.5 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 | 285,775 | |
| -1 | -285,775 |
Now, we try dividing 285,775 by 3:
285,775 ÷ 3 = 95,258.3333
If the quotient is a whole number, then 3 and 95,258.3333 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 | 285,775 | |
| -1 | -285,775 |
Let's try dividing by 4:
285,775 ÷ 4 = 71,443.75
If the quotient is a whole number, then 4 and 71,443.75 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 | 285,775 | |
| -1 | 285,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 25 | 35 | 71 | 115 | 161 | 175 | 355 | 497 | 575 | 805 | 1,633 | 1,775 | 2,485 | 4,025 | 8,165 | 11,431 | 12,425 | 40,825 | 57,155 | 285,775 |
| -1 | -5 | -7 | -23 | -25 | -35 | -71 | -115 | -161 | -175 | -355 | -497 | -575 | -805 | -1,633 | -1,775 | -2,485 | -4,025 | -8,165 | -11,431 | -12,425 | -40,825 | -57,155 | -285,775 |
