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 14,678,485, 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 | 14,678,485 | |
| -1 | -14,678,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,678,485.
Example:
1 x 14,678,485 = 14,678,485
and
-1 x -14,678,485 = 14,678,485
Notice both answers equal 14,678,485
With that explanation out of the way, let's continue. Next, we take the number 14,678,485 and divide it by 2:
14,678,485 ÷ 2 = 7,339,242.5
If the quotient is a whole number, then 2 and 7,339,242.5 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 | 14,678,485 | |
| -1 | -14,678,485 |
Now, we try dividing 14,678,485 by 3:
14,678,485 ÷ 3 = 4,892,828.3333
If the quotient is a whole number, then 3 and 4,892,828.3333 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 | 14,678,485 | |
| -1 | -14,678,485 |
Let's try dividing by 4:
14,678,485 ÷ 4 = 3,669,621.25
If the quotient is a whole number, then 4 and 3,669,621.25 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 | 14,678,485 | |
| -1 | 14,678,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 109 | 115 | 545 | 1,171 | 2,507 | 5,855 | 12,535 | 26,933 | 127,639 | 134,665 | 638,195 | 2,935,697 | 14,678,485 |
| -1 | -5 | -23 | -109 | -115 | -545 | -1,171 | -2,507 | -5,855 | -12,535 | -26,933 | -127,639 | -134,665 | -638,195 | -2,935,697 | -14,678,485 |
