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 18,480,875, 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 | 18,480,875 | |
| -1 | -18,480,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,480,875.
Example:
1 x 18,480,875 = 18,480,875
and
-1 x -18,480,875 = 18,480,875
Notice both answers equal 18,480,875
With that explanation out of the way, let's continue. Next, we take the number 18,480,875 and divide it by 2:
18,480,875 ÷ 2 = 9,240,437.5
If the quotient is a whole number, then 2 and 9,240,437.5 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 | 18,480,875 | |
| -1 | -18,480,875 |
Now, we try dividing 18,480,875 by 3:
18,480,875 ÷ 3 = 6,160,291.6667
If the quotient is a whole number, then 3 and 6,160,291.6667 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 | 18,480,875 | |
| -1 | -18,480,875 |
Let's try dividing by 4:
18,480,875 ÷ 4 = 4,620,218.75
If the quotient is a whole number, then 4 and 4,620,218.75 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 | 18,480,875 | |
| -1 | 18,480,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 21,121 | 105,605 | 147,847 | 528,025 | 739,235 | 2,640,125 | 3,696,175 | 18,480,875 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -21,121 | -105,605 | -147,847 | -528,025 | -739,235 | -2,640,125 | -3,696,175 | -18,480,875 |
