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 15,176,125, 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 | 15,176,125 | |
| -1 | -15,176,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,176,125.
Example:
1 x 15,176,125 = 15,176,125
and
-1 x -15,176,125 = 15,176,125
Notice both answers equal 15,176,125
With that explanation out of the way, let's continue. Next, we take the number 15,176,125 and divide it by 2:
15,176,125 ÷ 2 = 7,588,062.5
If the quotient is a whole number, then 2 and 7,588,062.5 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 | 15,176,125 | |
| -1 | -15,176,125 |
Now, we try dividing 15,176,125 by 3:
15,176,125 ÷ 3 = 5,058,708.3333
If the quotient is a whole number, then 3 and 5,058,708.3333 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 | 15,176,125 | |
| -1 | -15,176,125 |
Let's try dividing by 4:
15,176,125 ÷ 4 = 3,794,031.25
If the quotient is a whole number, then 4 and 3,794,031.25 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 | 15,176,125 | |
| -1 | 15,176,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 167 | 727 | 835 | 3,635 | 4,175 | 18,175 | 20,875 | 90,875 | 121,409 | 607,045 | 3,035,225 | 15,176,125 |
| -1 | -5 | -25 | -125 | -167 | -727 | -835 | -3,635 | -4,175 | -18,175 | -20,875 | -90,875 | -121,409 | -607,045 | -3,035,225 | -15,176,125 |
