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 320,103,113, 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 | 320,103,113 | |
| -1 | -320,103,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 320,103,113.
Example:
1 x 320,103,113 = 320,103,113
and
-1 x -320,103,113 = 320,103,113
Notice both answers equal 320,103,113
With that explanation out of the way, let's continue. Next, we take the number 320,103,113 and divide it by 2:
320,103,113 ÷ 2 = 160,051,556.5
If the quotient is a whole number, then 2 and 160,051,556.5 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 | 320,103,113 | |
| -1 | -320,103,113 |
Now, we try dividing 320,103,113 by 3:
320,103,113 ÷ 3 = 106,701,037.6667
If the quotient is a whole number, then 3 and 106,701,037.6667 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 | 320,103,113 | |
| -1 | -320,103,113 |
Let's try dividing by 4:
320,103,113 ÷ 4 = 80,025,778.25
If the quotient is a whole number, then 4 and 80,025,778.25 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 | 320,103,113 | |
| -1 | 320,103,113 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 317 | 451 | 2,239 | 3,487 | 12,997 | 24,629 | 91,799 | 142,967 | 709,763 | 1,009,789 | 7,807,393 | 29,100,283 | 320,103,113 |
| -1 | -11 | -41 | -317 | -451 | -2,239 | -3,487 | -12,997 | -24,629 | -91,799 | -142,967 | -709,763 | -1,009,789 | -7,807,393 | -29,100,283 | -320,103,113 |
