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 13,175,375, 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 | 13,175,375 | |
| -1 | -13,175,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,175,375.
Example:
1 x 13,175,375 = 13,175,375
and
-1 x -13,175,375 = 13,175,375
Notice both answers equal 13,175,375
With that explanation out of the way, let's continue. Next, we take the number 13,175,375 and divide it by 2:
13,175,375 ÷ 2 = 6,587,687.5
If the quotient is a whole number, then 2 and 6,587,687.5 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 | 13,175,375 | |
| -1 | -13,175,375 |
Now, we try dividing 13,175,375 by 3:
13,175,375 ÷ 3 = 4,391,791.6667
If the quotient is a whole number, then 3 and 4,391,791.6667 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 | 13,175,375 | |
| -1 | -13,175,375 |
Let's try dividing by 4:
13,175,375 ÷ 4 = 3,293,843.75
If the quotient is a whole number, then 4 and 3,293,843.75 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 | 13,175,375 | |
| -1 | 13,175,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 109 | 125 | 545 | 967 | 2,725 | 4,835 | 13,625 | 24,175 | 105,403 | 120,875 | 527,015 | 2,635,075 | 13,175,375 |
| -1 | -5 | -25 | -109 | -125 | -545 | -967 | -2,725 | -4,835 | -13,625 | -24,175 | -105,403 | -120,875 | -527,015 | -2,635,075 | -13,175,375 |
