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 17,924,153, 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 | 17,924,153 | |
| -1 | -17,924,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,924,153.
Example:
1 x 17,924,153 = 17,924,153
and
-1 x -17,924,153 = 17,924,153
Notice both answers equal 17,924,153
With that explanation out of the way, let's continue. Next, we take the number 17,924,153 and divide it by 2:
17,924,153 ÷ 2 = 8,962,076.5
If the quotient is a whole number, then 2 and 8,962,076.5 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 | 17,924,153 | |
| -1 | -17,924,153 |
Now, we try dividing 17,924,153 by 3:
17,924,153 ÷ 3 = 5,974,717.6667
If the quotient is a whole number, then 3 and 5,974,717.6667 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 | 17,924,153 | |
| -1 | -17,924,153 |
Let's try dividing by 4:
17,924,153 ÷ 4 = 4,481,038.25
If the quotient is a whole number, then 4 and 4,481,038.25 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 | 17,924,153 | |
| -1 | 17,924,153 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 151 | 299 | 397 | 1,963 | 3,473 | 5,161 | 9,131 | 45,149 | 59,947 | 118,703 | 779,311 | 1,378,781 | 17,924,153 |
| -1 | -13 | -23 | -151 | -299 | -397 | -1,963 | -3,473 | -5,161 | -9,131 | -45,149 | -59,947 | -118,703 | -779,311 | -1,378,781 | -17,924,153 |
