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 14,325,155, 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 | 14,325,155 | |
| -1 | -14,325,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,325,155.
Example:
1 x 14,325,155 = 14,325,155
and
-1 x -14,325,155 = 14,325,155
Notice both answers equal 14,325,155
With that explanation out of the way, let's continue. Next, we take the number 14,325,155 and divide it by 2:
14,325,155 ÷ 2 = 7,162,577.5
If the quotient is a whole number, then 2 and 7,162,577.5 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 | 14,325,155 | |
| -1 | -14,325,155 |
Now, we try dividing 14,325,155 by 3:
14,325,155 ÷ 3 = 4,775,051.6667
If the quotient is a whole number, then 3 and 4,775,051.6667 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 | 14,325,155 | |
| -1 | -14,325,155 |
Let's try dividing by 4:
14,325,155 ÷ 4 = 3,581,288.75
If the quotient is a whole number, then 4 and 3,581,288.75 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 | 14,325,155 | |
| -1 | 14,325,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 73 | 365 | 949 | 3,019 | 4,745 | 15,095 | 39,247 | 196,235 | 220,387 | 1,101,935 | 2,865,031 | 14,325,155 |
| -1 | -5 | -13 | -65 | -73 | -365 | -949 | -3,019 | -4,745 | -15,095 | -39,247 | -196,235 | -220,387 | -1,101,935 | -2,865,031 | -14,325,155 |
