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 18,026,675, 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 | 18,026,675 | |
| -1 | -18,026,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,026,675.
Example:
1 x 18,026,675 = 18,026,675
and
-1 x -18,026,675 = 18,026,675
Notice both answers equal 18,026,675
With that explanation out of the way, let's continue. Next, we take the number 18,026,675 and divide it by 2:
18,026,675 ÷ 2 = 9,013,337.5
If the quotient is a whole number, then 2 and 9,013,337.5 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 | 18,026,675 | |
| -1 | -18,026,675 |
Now, we try dividing 18,026,675 by 3:
18,026,675 ÷ 3 = 6,008,891.6667
If the quotient is a whole number, then 3 and 6,008,891.6667 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 | 18,026,675 | |
| -1 | -18,026,675 |
Let's try dividing by 4:
18,026,675 ÷ 4 = 4,506,668.75
If the quotient is a whole number, then 4 and 4,506,668.75 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 | 18,026,675 | |
| -1 | 18,026,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 41 | 43 | 205 | 215 | 409 | 1,025 | 1,075 | 1,763 | 2,045 | 8,815 | 10,225 | 16,769 | 17,587 | 44,075 | 83,845 | 87,935 | 419,225 | 439,675 | 721,067 | 3,605,335 | 18,026,675 |
| -1 | -5 | -25 | -41 | -43 | -205 | -215 | -409 | -1,025 | -1,075 | -1,763 | -2,045 | -8,815 | -10,225 | -16,769 | -17,587 | -44,075 | -83,845 | -87,935 | -419,225 | -439,675 | -721,067 | -3,605,335 | -18,026,675 |
