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 14,287,145, 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 | 14,287,145 | |
| -1 | -14,287,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,287,145.
Example:
1 x 14,287,145 = 14,287,145
and
-1 x -14,287,145 = 14,287,145
Notice both answers equal 14,287,145
With that explanation out of the way, let's continue. Next, we take the number 14,287,145 and divide it by 2:
14,287,145 ÷ 2 = 7,143,572.5
If the quotient is a whole number, then 2 and 7,143,572.5 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 | 14,287,145 | |
| -1 | -14,287,145 |
Now, we try dividing 14,287,145 by 3:
14,287,145 ÷ 3 = 4,762,381.6667
If the quotient is a whole number, then 3 and 4,762,381.6667 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 | 14,287,145 | |
| -1 | -14,287,145 |
Let's try dividing by 4:
14,287,145 ÷ 4 = 3,571,786.25
If the quotient is a whole number, then 4 and 3,571,786.25 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 | 14,287,145 | |
| -1 | 14,287,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 59 | 95 | 295 | 1,121 | 2,549 | 5,605 | 12,745 | 48,431 | 150,391 | 242,155 | 751,955 | 2,857,429 | 14,287,145 |
| -1 | -5 | -19 | -59 | -95 | -295 | -1,121 | -2,549 | -5,605 | -12,745 | -48,431 | -150,391 | -242,155 | -751,955 | -2,857,429 | -14,287,145 |
