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 16,697,345, 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 | 16,697,345 | |
| -1 | -16,697,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,697,345.
Example:
1 x 16,697,345 = 16,697,345
and
-1 x -16,697,345 = 16,697,345
Notice both answers equal 16,697,345
With that explanation out of the way, let's continue. Next, we take the number 16,697,345 and divide it by 2:
16,697,345 ÷ 2 = 8,348,672.5
If the quotient is a whole number, then 2 and 8,348,672.5 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 | 16,697,345 | |
| -1 | -16,697,345 |
Now, we try dividing 16,697,345 by 3:
16,697,345 ÷ 3 = 5,565,781.6667
If the quotient is a whole number, then 3 and 5,565,781.6667 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 | 16,697,345 | |
| -1 | -16,697,345 |
Let's try dividing by 4:
16,697,345 ÷ 4 = 4,174,336.25
If the quotient is a whole number, then 4 and 4,174,336.25 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 | 16,697,345 | |
| -1 | 16,697,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 373 | 1,279 | 1,865 | 2,611 | 6,395 | 8,953 | 13,055 | 44,765 | 477,067 | 2,385,335 | 3,339,469 | 16,697,345 |
| -1 | -5 | -7 | -35 | -373 | -1,279 | -1,865 | -2,611 | -6,395 | -8,953 | -13,055 | -44,765 | -477,067 | -2,385,335 | -3,339,469 | -16,697,345 |
