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 313,775, 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 | 313,775 | |
| -1 | -313,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 313,775.
Example:
1 x 313,775 = 313,775
and
-1 x -313,775 = 313,775
Notice both answers equal 313,775
With that explanation out of the way, let's continue. Next, we take the number 313,775 and divide it by 2:
313,775 ÷ 2 = 156,887.5
If the quotient is a whole number, then 2 and 156,887.5 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 | 313,775 | |
| -1 | -313,775 |
Now, we try dividing 313,775 by 3:
313,775 ÷ 3 = 104,591.6667
If the quotient is a whole number, then 3 and 104,591.6667 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 | 313,775 | |
| -1 | -313,775 |
Let's try dividing by 4:
313,775 ÷ 4 = 78,443.75
If the quotient is a whole number, then 4 and 78,443.75 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 | 313,775 | |
| -1 | 313,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 163 | 175 | 275 | 385 | 815 | 1,141 | 1,793 | 1,925 | 4,075 | 5,705 | 8,965 | 12,551 | 28,525 | 44,825 | 62,755 | 313,775 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -163 | -175 | -275 | -385 | -815 | -1,141 | -1,793 | -1,925 | -4,075 | -5,705 | -8,965 | -12,551 | -28,525 | -44,825 | -62,755 | -313,775 |
