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 320,110,297, 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 | 320,110,297 | |
| -1 | -320,110,297 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 320,110,297.
Example:
1 x 320,110,297 = 320,110,297
and
-1 x -320,110,297 = 320,110,297
Notice both answers equal 320,110,297
With that explanation out of the way, let's continue. Next, we take the number 320,110,297 and divide it by 2:
320,110,297 ÷ 2 = 160,055,148.5
If the quotient is a whole number, then 2 and 160,055,148.5 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 | 320,110,297 | |
| -1 | -320,110,297 |
Now, we try dividing 320,110,297 by 3:
320,110,297 ÷ 3 = 106,703,432.3333
If the quotient is a whole number, then 3 and 106,703,432.3333 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 | 320,110,297 | |
| -1 | -320,110,297 |
Let's try dividing by 4:
320,110,297 ÷ 4 = 80,027,574.25
If the quotient is a whole number, then 4 and 80,027,574.25 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 | 320,110,297 | |
| -1 | 320,110,297 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 299 | 421 | 2,543 | 5,473 | 9,683 | 33,059 | 58,489 | 125,879 | 760,357 | 1,070,603 | 13,917,839 | 24,623,869 | 320,110,297 |
| -1 | -13 | -23 | -299 | -421 | -2,543 | -5,473 | -9,683 | -33,059 | -58,489 | -125,879 | -760,357 | -1,070,603 | -13,917,839 | -24,623,869 | -320,110,297 |
