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 17,951,263, 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 | 17,951,263 | |
| -1 | -17,951,263 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,951,263.
Example:
1 x 17,951,263 = 17,951,263
and
-1 x -17,951,263 = 17,951,263
Notice both answers equal 17,951,263
With that explanation out of the way, let's continue. Next, we take the number 17,951,263 and divide it by 2:
17,951,263 ÷ 2 = 8,975,631.5
If the quotient is a whole number, then 2 and 8,975,631.5 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 | 17,951,263 | |
| -1 | -17,951,263 |
Now, we try dividing 17,951,263 by 3:
17,951,263 ÷ 3 = 5,983,754.3333
If the quotient is a whole number, then 3 and 5,983,754.3333 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 | 17,951,263 | |
| -1 | -17,951,263 |
Let's try dividing by 4:
17,951,263 ÷ 4 = 4,487,815.75
If the quotient is a whole number, then 4 and 4,487,815.75 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 | 17,951,263 | |
| -1 | 17,951,263 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 61 | 341 | 671 | 863 | 1,891 | 9,493 | 20,801 | 26,753 | 52,643 | 294,283 | 579,073 | 1,631,933 | 17,951,263 |
| -1 | -11 | -31 | -61 | -341 | -671 | -863 | -1,891 | -9,493 | -20,801 | -26,753 | -52,643 | -294,283 | -579,073 | -1,631,933 | -17,951,263 |
