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 16,113,097, 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 | 16,113,097 | |
| -1 | -16,113,097 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,113,097.
Example:
1 x 16,113,097 = 16,113,097
and
-1 x -16,113,097 = 16,113,097
Notice both answers equal 16,113,097
With that explanation out of the way, let's continue. Next, we take the number 16,113,097 and divide it by 2:
16,113,097 ÷ 2 = 8,056,548.5
If the quotient is a whole number, then 2 and 8,056,548.5 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 | 16,113,097 | |
| -1 | -16,113,097 |
Now, we try dividing 16,113,097 by 3:
16,113,097 ÷ 3 = 5,371,032.3333
If the quotient is a whole number, then 3 and 5,371,032.3333 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 | 16,113,097 | |
| -1 | -16,113,097 |
Let's try dividing by 4:
16,113,097 ÷ 4 = 4,028,274.25
If the quotient is a whole number, then 4 and 4,028,274.25 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 | 16,113,097 | |
| -1 | 16,113,097 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 16,097 | 112,679 | 177,067 | 209,261 | 1,239,469 | 1,464,827 | 2,301,871 | 16,113,097 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -16,097 | -112,679 | -177,067 | -209,261 | -1,239,469 | -1,464,827 | -2,301,871 | -16,113,097 |
