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 24,213,733, 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 | 24,213,733 | |
| -1 | -24,213,733 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,213,733.
Example:
1 x 24,213,733 = 24,213,733
and
-1 x -24,213,733 = 24,213,733
Notice both answers equal 24,213,733
With that explanation out of the way, let's continue. Next, we take the number 24,213,733 and divide it by 2:
24,213,733 ÷ 2 = 12,106,866.5
If the quotient is a whole number, then 2 and 12,106,866.5 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 | 24,213,733 | |
| -1 | -24,213,733 |
Now, we try dividing 24,213,733 by 3:
24,213,733 ÷ 3 = 8,071,244.3333
If the quotient is a whole number, then 3 and 8,071,244.3333 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 | 24,213,733 | |
| -1 | -24,213,733 |
Let's try dividing by 4:
24,213,733 ÷ 4 = 6,053,433.25
If the quotient is a whole number, then 4 and 6,053,433.25 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 | 24,213,733 | |
| -1 | 24,213,733 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 67 | 437 | 827 | 1,273 | 1,541 | 15,713 | 19,021 | 29,279 | 55,409 | 361,399 | 1,052,771 | 1,274,407 | 24,213,733 |
| -1 | -19 | -23 | -67 | -437 | -827 | -1,273 | -1,541 | -15,713 | -19,021 | -29,279 | -55,409 | -361,399 | -1,052,771 | -1,274,407 | -24,213,733 |
