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 16,753,231, 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 | 16,753,231 | |
| -1 | -16,753,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,753,231.
Example:
1 x 16,753,231 = 16,753,231
and
-1 x -16,753,231 = 16,753,231
Notice both answers equal 16,753,231
With that explanation out of the way, let's continue. Next, we take the number 16,753,231 and divide it by 2:
16,753,231 ÷ 2 = 8,376,615.5
If the quotient is a whole number, then 2 and 8,376,615.5 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 | 16,753,231 | |
| -1 | -16,753,231 |
Now, we try dividing 16,753,231 by 3:
16,753,231 ÷ 3 = 5,584,410.3333
If the quotient is a whole number, then 3 and 5,584,410.3333 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 | 16,753,231 | |
| -1 | -16,753,231 |
Let's try dividing by 4:
16,753,231 ÷ 4 = 4,188,307.75
If the quotient is a whole number, then 4 and 4,188,307.75 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 | 16,753,231 | |
| -1 | 16,753,231 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 71 | 209 | 781 | 1,129 | 1,349 | 12,419 | 14,839 | 21,451 | 80,159 | 235,961 | 881,749 | 1,523,021 | 16,753,231 |
| -1 | -11 | -19 | -71 | -209 | -781 | -1,129 | -1,349 | -12,419 | -14,839 | -21,451 | -80,159 | -235,961 | -881,749 | -1,523,021 | -16,753,231 |
