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 18,623,125, 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 | 18,623,125 | |
| -1 | -18,623,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,623,125.
Example:
1 x 18,623,125 = 18,623,125
and
-1 x -18,623,125 = 18,623,125
Notice both answers equal 18,623,125
With that explanation out of the way, let's continue. Next, we take the number 18,623,125 and divide it by 2:
18,623,125 ÷ 2 = 9,311,562.5
If the quotient is a whole number, then 2 and 9,311,562.5 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 | 18,623,125 | |
| -1 | -18,623,125 |
Now, we try dividing 18,623,125 by 3:
18,623,125 ÷ 3 = 6,207,708.3333
If the quotient is a whole number, then 3 and 6,207,708.3333 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 | 18,623,125 | |
| -1 | -18,623,125 |
Let's try dividing by 4:
18,623,125 ÷ 4 = 4,655,781.25
If the quotient is a whole number, then 4 and 4,655,781.25 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 | 18,623,125 | |
| -1 | 18,623,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 83 | 125 | 359 | 415 | 625 | 1,795 | 2,075 | 8,975 | 10,375 | 29,797 | 44,875 | 51,875 | 148,985 | 224,375 | 744,925 | 3,724,625 | 18,623,125 |
| -1 | -5 | -25 | -83 | -125 | -359 | -415 | -625 | -1,795 | -2,075 | -8,975 | -10,375 | -29,797 | -44,875 | -51,875 | -148,985 | -224,375 | -744,925 | -3,724,625 | -18,623,125 |
