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 320,103,029, 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 | 320,103,029 | |
| -1 | -320,103,029 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 320,103,029.
Example:
1 x 320,103,029 = 320,103,029
and
-1 x -320,103,029 = 320,103,029
Notice both answers equal 320,103,029
With that explanation out of the way, let's continue. Next, we take the number 320,103,029 and divide it by 2:
320,103,029 ÷ 2 = 160,051,514.5
If the quotient is a whole number, then 2 and 160,051,514.5 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 | 320,103,029 | |
| -1 | -320,103,029 |
Now, we try dividing 320,103,029 by 3:
320,103,029 ÷ 3 = 106,701,009.6667
If the quotient is a whole number, then 3 and 106,701,009.6667 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 | 320,103,029 | |
| -1 | -320,103,029 |
Let's try dividing by 4:
320,103,029 ÷ 4 = 80,025,757.25
If the quotient is a whole number, then 4 and 80,025,757.25 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 | 320,103,029 | |
| -1 | 320,103,029 |
If you did it right, you will end up with this table:
| 1 | 23 | 73 | 83 | 1,679 | 1,909 | 2,297 | 6,059 | 52,831 | 139,357 | 167,681 | 190,651 | 3,856,663 | 4,384,973 | 13,917,523 | 320,103,029 |
| -1 | -23 | -73 | -83 | -1,679 | -1,909 | -2,297 | -6,059 | -52,831 | -139,357 | -167,681 | -190,651 | -3,856,663 | -4,384,973 | -13,917,523 | -320,103,029 |
