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 245,735, 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 | 245,735 | |
| -1 | -245,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 245,735.
Example:
1 x 245,735 = 245,735
and
-1 x -245,735 = 245,735
Notice both answers equal 245,735
With that explanation out of the way, let's continue. Next, we take the number 245,735 and divide it by 2:
245,735 ÷ 2 = 122,867.5
If the quotient is a whole number, then 2 and 122,867.5 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 | 245,735 | |
| -1 | -245,735 |
Now, we try dividing 245,735 by 3:
245,735 ÷ 3 = 81,911.6667
If the quotient is a whole number, then 3 and 81,911.6667 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 | 245,735 | |
| -1 | -245,735 |
Let's try dividing by 4:
245,735 ÷ 4 = 61,433.75
If the quotient is a whole number, then 4 and 61,433.75 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 | 245,735 | |
| -1 | 245,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 49 | 59 | 85 | 119 | 245 | 295 | 413 | 595 | 833 | 1,003 | 2,065 | 2,891 | 4,165 | 5,015 | 7,021 | 14,455 | 35,105 | 49,147 | 245,735 |
| -1 | -5 | -7 | -17 | -35 | -49 | -59 | -85 | -119 | -245 | -295 | -413 | -595 | -833 | -1,003 | -2,065 | -2,891 | -4,165 | -5,015 | -7,021 | -14,455 | -35,105 | -49,147 | -245,735 |
