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 348,985, 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 | 348,985 | |
| -1 | -348,985 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 348,985.
Example:
1 x 348,985 = 348,985
and
-1 x -348,985 = 348,985
Notice both answers equal 348,985
With that explanation out of the way, let's continue. Next, we take the number 348,985 and divide it by 2:
348,985 ÷ 2 = 174,492.5
If the quotient is a whole number, then 2 and 174,492.5 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 | 348,985 | |
| -1 | -348,985 |
Now, we try dividing 348,985 by 3:
348,985 ÷ 3 = 116,328.3333
If the quotient is a whole number, then 3 and 116,328.3333 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 | 348,985 | |
| -1 | -348,985 |
Let's try dividing by 4:
348,985 ÷ 4 = 87,246.25
If the quotient is a whole number, then 4 and 87,246.25 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 | 348,985 | |
| -1 | 348,985 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 59 | 65 | 91 | 169 | 295 | 413 | 455 | 767 | 845 | 1,183 | 2,065 | 3,835 | 5,369 | 5,915 | 9,971 | 26,845 | 49,855 | 69,797 | 348,985 |
| -1 | -5 | -7 | -13 | -35 | -59 | -65 | -91 | -169 | -295 | -413 | -455 | -767 | -845 | -1,183 | -2,065 | -3,835 | -5,369 | -5,915 | -9,971 | -26,845 | -49,855 | -69,797 | -348,985 |
