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 17,445,623, 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 | 17,445,623 | |
| -1 | -17,445,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,445,623.
Example:
1 x 17,445,623 = 17,445,623
and
-1 x -17,445,623 = 17,445,623
Notice both answers equal 17,445,623
With that explanation out of the way, let's continue. Next, we take the number 17,445,623 and divide it by 2:
17,445,623 ÷ 2 = 8,722,811.5
If the quotient is a whole number, then 2 and 8,722,811.5 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 | 17,445,623 | |
| -1 | -17,445,623 |
Now, we try dividing 17,445,623 by 3:
17,445,623 ÷ 3 = 5,815,207.6667
If the quotient is a whole number, then 3 and 5,815,207.6667 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 | 17,445,623 | |
| -1 | -17,445,623 |
Let's try dividing by 4:
17,445,623 ÷ 4 = 4,361,405.75
If the quotient is a whole number, then 4 and 4,361,405.75 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 | 17,445,623 | |
| -1 | 17,445,623 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 71 | 461 | 533 | 923 | 2,911 | 5,993 | 18,901 | 32,731 | 37,843 | 245,713 | 425,503 | 1,341,971 | 17,445,623 |
| -1 | -13 | -41 | -71 | -461 | -533 | -923 | -2,911 | -5,993 | -18,901 | -32,731 | -37,843 | -245,713 | -425,503 | -1,341,971 | -17,445,623 |
