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 16,114,553, 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 | 16,114,553 | |
| -1 | -16,114,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,114,553.
Example:
1 x 16,114,553 = 16,114,553
and
-1 x -16,114,553 = 16,114,553
Notice both answers equal 16,114,553
With that explanation out of the way, let's continue. Next, we take the number 16,114,553 and divide it by 2:
16,114,553 ÷ 2 = 8,057,276.5
If the quotient is a whole number, then 2 and 8,057,276.5 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 | 16,114,553 | |
| -1 | -16,114,553 |
Now, we try dividing 16,114,553 by 3:
16,114,553 ÷ 3 = 5,371,517.6667
If the quotient is a whole number, then 3 and 5,371,517.6667 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 | 16,114,553 | |
| -1 | -16,114,553 |
Let's try dividing by 4:
16,114,553 ÷ 4 = 4,028,638.25
If the quotient is a whole number, then 4 and 4,028,638.25 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 | 16,114,553 | |
| -1 | 16,114,553 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 61 | 91 | 427 | 793 | 2,903 | 5,551 | 20,321 | 37,739 | 177,083 | 264,173 | 1,239,581 | 2,302,079 | 16,114,553 |
| -1 | -7 | -13 | -61 | -91 | -427 | -793 | -2,903 | -5,551 | -20,321 | -37,739 | -177,083 | -264,173 | -1,239,581 | -2,302,079 | -16,114,553 |
