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 16,114,451, 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 | 16,114,451 | |
| -1 | -16,114,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,114,451.
Example:
1 x 16,114,451 = 16,114,451
and
-1 x -16,114,451 = 16,114,451
Notice both answers equal 16,114,451
With that explanation out of the way, let's continue. Next, we take the number 16,114,451 and divide it by 2:
16,114,451 ÷ 2 = 8,057,225.5
If the quotient is a whole number, then 2 and 8,057,225.5 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 | 16,114,451 | |
| -1 | -16,114,451 |
Now, we try dividing 16,114,451 by 3:
16,114,451 ÷ 3 = 5,371,483.6667
If the quotient is a whole number, then 3 and 5,371,483.6667 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 | 16,114,451 | |
| -1 | -16,114,451 |
Let's try dividing by 4:
16,114,451 ÷ 4 = 4,028,612.75
If the quotient is a whole number, then 4 and 4,028,612.75 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 | 16,114,451 | |
| -1 | 16,114,451 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 109 | 251 | 589 | 2,071 | 3,379 | 4,769 | 7,781 | 27,359 | 64,201 | 147,839 | 519,821 | 848,129 | 16,114,451 |
| -1 | -19 | -31 | -109 | -251 | -589 | -2,071 | -3,379 | -4,769 | -7,781 | -27,359 | -64,201 | -147,839 | -519,821 | -848,129 | -16,114,451 |
