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 13,473,163, 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 | 13,473,163 | |
| -1 | -13,473,163 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,473,163.
Example:
1 x 13,473,163 = 13,473,163
and
-1 x -13,473,163 = 13,473,163
Notice both answers equal 13,473,163
With that explanation out of the way, let's continue. Next, we take the number 13,473,163 and divide it by 2:
13,473,163 ÷ 2 = 6,736,581.5
If the quotient is a whole number, then 2 and 6,736,581.5 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 | 13,473,163 | |
| -1 | -13,473,163 |
Now, we try dividing 13,473,163 by 3:
13,473,163 ÷ 3 = 4,491,054.3333
If the quotient is a whole number, then 3 and 4,491,054.3333 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 | 13,473,163 | |
| -1 | -13,473,163 |
Let's try dividing by 4:
13,473,163 ÷ 4 = 3,368,290.75
If the quotient is a whole number, then 4 and 3,368,290.75 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 | 13,473,163 | |
| -1 | 13,473,163 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 109 | 187 | 661 | 1,199 | 1,853 | 7,271 | 11,237 | 20,383 | 72,049 | 123,607 | 792,539 | 1,224,833 | 13,473,163 |
| -1 | -11 | -17 | -109 | -187 | -661 | -1,199 | -1,853 | -7,271 | -11,237 | -20,383 | -72,049 | -123,607 | -792,539 | -1,224,833 | -13,473,163 |
