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 17,530,439, 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 | 17,530,439 | |
| -1 | -17,530,439 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,530,439.
Example:
1 x 17,530,439 = 17,530,439
and
-1 x -17,530,439 = 17,530,439
Notice both answers equal 17,530,439
With that explanation out of the way, let's continue. Next, we take the number 17,530,439 and divide it by 2:
17,530,439 ÷ 2 = 8,765,219.5
If the quotient is a whole number, then 2 and 8,765,219.5 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 | 17,530,439 | |
| -1 | -17,530,439 |
Now, we try dividing 17,530,439 by 3:
17,530,439 ÷ 3 = 5,843,479.6667
If the quotient is a whole number, then 3 and 5,843,479.6667 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 | 17,530,439 | |
| -1 | -17,530,439 |
Let's try dividing by 4:
17,530,439 ÷ 4 = 4,382,609.75
If the quotient is a whole number, then 4 and 4,382,609.75 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 | 17,530,439 | |
| -1 | 17,530,439 |
If you did it right, you will end up with this table:
| 1 | 23 | 53 | 73 | 197 | 1,219 | 1,679 | 3,869 | 4,531 | 10,441 | 14,381 | 88,987 | 240,143 | 330,763 | 762,193 | 17,530,439 |
| -1 | -23 | -53 | -73 | -197 | -1,219 | -1,679 | -3,869 | -4,531 | -10,441 | -14,381 | -88,987 | -240,143 | -330,763 | -762,193 | -17,530,439 |
