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 201,329,303, 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 | 201,329,303 | |
| -1 | -201,329,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,329,303.
Example:
1 x 201,329,303 = 201,329,303
and
-1 x -201,329,303 = 201,329,303
Notice both answers equal 201,329,303
With that explanation out of the way, let's continue. Next, we take the number 201,329,303 and divide it by 2:
201,329,303 ÷ 2 = 100,664,651.5
If the quotient is a whole number, then 2 and 100,664,651.5 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 | 201,329,303 | |
| -1 | -201,329,303 |
Now, we try dividing 201,329,303 by 3:
201,329,303 ÷ 3 = 67,109,767.6667
If the quotient is a whole number, then 3 and 67,109,767.6667 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 | 201,329,303 | |
| -1 | -201,329,303 |
Let's try dividing by 4:
201,329,303 ÷ 4 = 50,332,325.75
If the quotient is a whole number, then 4 and 50,332,325.75 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 | 201,329,303 | |
| -1 | 201,329,303 |
If you did it right, you will end up with this table:
| 1 | 7 | 89 | 461 | 623 | 701 | 3,227 | 4,907 | 41,029 | 62,389 | 287,203 | 323,161 | 436,723 | 2,262,127 | 28,761,329 | 201,329,303 |
| -1 | -7 | -89 | -461 | -623 | -701 | -3,227 | -4,907 | -41,029 | -62,389 | -287,203 | -323,161 | -436,723 | -2,262,127 | -28,761,329 | -201,329,303 |
