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 14,513,213, 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 | 14,513,213 | |
| -1 | -14,513,213 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,513,213.
Example:
1 x 14,513,213 = 14,513,213
and
-1 x -14,513,213 = 14,513,213
Notice both answers equal 14,513,213
With that explanation out of the way, let's continue. Next, we take the number 14,513,213 and divide it by 2:
14,513,213 ÷ 2 = 7,256,606.5
If the quotient is a whole number, then 2 and 7,256,606.5 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 | 14,513,213 | |
| -1 | -14,513,213 |
Now, we try dividing 14,513,213 by 3:
14,513,213 ÷ 3 = 4,837,737.6667
If the quotient is a whole number, then 3 and 4,837,737.6667 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 | 14,513,213 | |
| -1 | -14,513,213 |
Let's try dividing by 4:
14,513,213 ÷ 4 = 3,628,303.25
If the quotient is a whole number, then 4 and 3,628,303.25 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 | 14,513,213 | |
| -1 | 14,513,213 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 37 | 143 | 169 | 211 | 407 | 481 | 1,859 | 2,321 | 2,743 | 5,291 | 6,253 | 7,807 | 30,173 | 35,659 | 68,783 | 85,877 | 101,491 | 392,249 | 1,116,401 | 1,319,383 | 14,513,213 |
| -1 | -11 | -13 | -37 | -143 | -169 | -211 | -407 | -481 | -1,859 | -2,321 | -2,743 | -5,291 | -6,253 | -7,807 | -30,173 | -35,659 | -68,783 | -85,877 | -101,491 | -392,249 | -1,116,401 | -1,319,383 | -14,513,213 |
