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 16,113,361, 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 | 16,113,361 | |
| -1 | -16,113,361 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,113,361.
Example:
1 x 16,113,361 = 16,113,361
and
-1 x -16,113,361 = 16,113,361
Notice both answers equal 16,113,361
With that explanation out of the way, let's continue. Next, we take the number 16,113,361 and divide it by 2:
16,113,361 ÷ 2 = 8,056,680.5
If the quotient is a whole number, then 2 and 8,056,680.5 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 | 16,113,361 | |
| -1 | -16,113,361 |
Now, we try dividing 16,113,361 by 3:
16,113,361 ÷ 3 = 5,371,120.3333
If the quotient is a whole number, then 3 and 5,371,120.3333 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 | 16,113,361 | |
| -1 | -16,113,361 |
Let's try dividing by 4:
16,113,361 ÷ 4 = 4,028,340.25
If the quotient is a whole number, then 4 and 4,028,340.25 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 | 16,113,361 | |
| -1 | 16,113,361 |
If you did it right, you will end up with this table:
| 1 | 11 | 89 | 109 | 151 | 979 | 1,199 | 1,661 | 9,701 | 13,439 | 16,459 | 106,711 | 147,829 | 181,049 | 1,464,851 | 16,113,361 |
| -1 | -11 | -89 | -109 | -151 | -979 | -1,199 | -1,661 | -9,701 | -13,439 | -16,459 | -106,711 | -147,829 | -181,049 | -1,464,851 | -16,113,361 |
