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 14,864,221, 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 | 14,864,221 | |
| -1 | -14,864,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,864,221.
Example:
1 x 14,864,221 = 14,864,221
and
-1 x -14,864,221 = 14,864,221
Notice both answers equal 14,864,221
With that explanation out of the way, let's continue. Next, we take the number 14,864,221 and divide it by 2:
14,864,221 ÷ 2 = 7,432,110.5
If the quotient is a whole number, then 2 and 7,432,110.5 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 | 14,864,221 | |
| -1 | -14,864,221 |
Now, we try dividing 14,864,221 by 3:
14,864,221 ÷ 3 = 4,954,740.3333
If the quotient is a whole number, then 3 and 4,954,740.3333 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 | 14,864,221 | |
| -1 | -14,864,221 |
Let's try dividing by 4:
14,864,221 ÷ 4 = 3,716,055.25
If the quotient is a whole number, then 4 and 3,716,055.25 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 | 14,864,221 | |
| -1 | 14,864,221 |
If you did it right, you will end up with this table:
| 1 | 31 | 53 | 83 | 109 | 1,643 | 2,573 | 3,379 | 4,399 | 5,777 | 9,047 | 136,369 | 179,087 | 280,457 | 479,491 | 14,864,221 |
| -1 | -31 | -53 | -83 | -109 | -1,643 | -2,573 | -3,379 | -4,399 | -5,777 | -9,047 | -136,369 | -179,087 | -280,457 | -479,491 | -14,864,221 |
