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 13,118,303, 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 | 13,118,303 | |
| -1 | -13,118,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,118,303.
Example:
1 x 13,118,303 = 13,118,303
and
-1 x -13,118,303 = 13,118,303
Notice both answers equal 13,118,303
With that explanation out of the way, let's continue. Next, we take the number 13,118,303 and divide it by 2:
13,118,303 ÷ 2 = 6,559,151.5
If the quotient is a whole number, then 2 and 6,559,151.5 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 | 13,118,303 | |
| -1 | -13,118,303 |
Now, we try dividing 13,118,303 by 3:
13,118,303 ÷ 3 = 4,372,767.6667
If the quotient is a whole number, then 3 and 4,372,767.6667 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 | 13,118,303 | |
| -1 | -13,118,303 |
Let's try dividing by 4:
13,118,303 ÷ 4 = 3,279,575.75
If the quotient is a whole number, then 4 and 3,279,575.75 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 | 13,118,303 | |
| -1 | 13,118,303 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 23 | 209 | 253 | 437 | 2,729 | 4,807 | 30,019 | 51,851 | 62,767 | 570,361 | 690,437 | 1,192,573 | 13,118,303 |
| -1 | -11 | -19 | -23 | -209 | -253 | -437 | -2,729 | -4,807 | -30,019 | -51,851 | -62,767 | -570,361 | -690,437 | -1,192,573 | -13,118,303 |
