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 13,148,803, 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 | 13,148,803 | |
| -1 | -13,148,803 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,148,803.
Example:
1 x 13,148,803 = 13,148,803
and
-1 x -13,148,803 = 13,148,803
Notice both answers equal 13,148,803
With that explanation out of the way, let's continue. Next, we take the number 13,148,803 and divide it by 2:
13,148,803 ÷ 2 = 6,574,401.5
If the quotient is a whole number, then 2 and 6,574,401.5 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 | 13,148,803 | |
| -1 | -13,148,803 |
Now, we try dividing 13,148,803 by 3:
13,148,803 ÷ 3 = 4,382,934.3333
If the quotient is a whole number, then 3 and 4,382,934.3333 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 | 13,148,803 | |
| -1 | -13,148,803 |
Let's try dividing by 4:
13,148,803 ÷ 4 = 3,287,200.75
If the quotient is a whole number, then 4 and 3,287,200.75 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 | 13,148,803 | |
| -1 | 13,148,803 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 149 | 179 | 493 | 2,533 | 3,043 | 4,321 | 5,191 | 26,671 | 73,457 | 88,247 | 453,407 | 773,459 | 13,148,803 |
| -1 | -17 | -29 | -149 | -179 | -493 | -2,533 | -3,043 | -4,321 | -5,191 | -26,671 | -73,457 | -88,247 | -453,407 | -773,459 | -13,148,803 |
