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 14,012,215, 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 | 14,012,215 | |
| -1 | -14,012,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,012,215.
Example:
1 x 14,012,215 = 14,012,215
and
-1 x -14,012,215 = 14,012,215
Notice both answers equal 14,012,215
With that explanation out of the way, let's continue. Next, we take the number 14,012,215 and divide it by 2:
14,012,215 ÷ 2 = 7,006,107.5
If the quotient is a whole number, then 2 and 7,006,107.5 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 | 14,012,215 | |
| -1 | -14,012,215 |
Now, we try dividing 14,012,215 by 3:
14,012,215 ÷ 3 = 4,670,738.3333
If the quotient is a whole number, then 3 and 4,670,738.3333 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 | 14,012,215 | |
| -1 | -14,012,215 |
Let's try dividing by 4:
14,012,215 ÷ 4 = 3,503,053.75
If the quotient is a whole number, then 4 and 3,503,053.75 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 | 14,012,215 | |
| -1 | 14,012,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 361 | 665 | 1,109 | 1,805 | 2,527 | 5,545 | 7,763 | 12,635 | 21,071 | 38,815 | 105,355 | 147,497 | 400,349 | 737,485 | 2,001,745 | 2,802,443 | 14,012,215 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -361 | -665 | -1,109 | -1,805 | -2,527 | -5,545 | -7,763 | -12,635 | -21,071 | -38,815 | -105,355 | -147,497 | -400,349 | -737,485 | -2,001,745 | -2,802,443 | -14,012,215 |
