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 17,737,291, 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 | 17,737,291 | |
| -1 | -17,737,291 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,737,291.
Example:
1 x 17,737,291 = 17,737,291
and
-1 x -17,737,291 = 17,737,291
Notice both answers equal 17,737,291
With that explanation out of the way, let's continue. Next, we take the number 17,737,291 and divide it by 2:
17,737,291 ÷ 2 = 8,868,645.5
If the quotient is a whole number, then 2 and 8,868,645.5 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 | 17,737,291 | |
| -1 | -17,737,291 |
Now, we try dividing 17,737,291 by 3:
17,737,291 ÷ 3 = 5,912,430.3333
If the quotient is a whole number, then 3 and 5,912,430.3333 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 | 17,737,291 | |
| -1 | -17,737,291 |
Let's try dividing by 4:
17,737,291 ÷ 4 = 4,434,322.75
If the quotient is a whole number, then 4 and 4,434,322.75 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 | 17,737,291 | |
| -1 | 17,737,291 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 71 | 143 | 781 | 923 | 1,747 | 10,153 | 19,217 | 22,711 | 124,037 | 249,821 | 1,364,407 | 1,612,481 | 17,737,291 |
| -1 | -11 | -13 | -71 | -143 | -781 | -923 | -1,747 | -10,153 | -19,217 | -22,711 | -124,037 | -249,821 | -1,364,407 | -1,612,481 | -17,737,291 |
