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 24,229,645, 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 | 24,229,645 | |
| -1 | -24,229,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,229,645.
Example:
1 x 24,229,645 = 24,229,645
and
-1 x -24,229,645 = 24,229,645
Notice both answers equal 24,229,645
With that explanation out of the way, let's continue. Next, we take the number 24,229,645 and divide it by 2:
24,229,645 ÷ 2 = 12,114,822.5
If the quotient is a whole number, then 2 and 12,114,822.5 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 | 24,229,645 | |
| -1 | -24,229,645 |
Now, we try dividing 24,229,645 by 3:
24,229,645 ÷ 3 = 8,076,548.3333
If the quotient is a whole number, then 3 and 8,076,548.3333 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 | 24,229,645 | |
| -1 | -24,229,645 |
Let's try dividing by 4:
24,229,645 ÷ 4 = 6,057,411.25
If the quotient is a whole number, then 4 and 6,057,411.25 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 | 24,229,645 | |
| -1 | 24,229,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 121 | 145 | 319 | 605 | 1,381 | 1,595 | 3,509 | 6,905 | 15,191 | 17,545 | 40,049 | 75,955 | 167,101 | 200,245 | 440,539 | 835,505 | 2,202,695 | 4,845,929 | 24,229,645 |
| -1 | -5 | -11 | -29 | -55 | -121 | -145 | -319 | -605 | -1,381 | -1,595 | -3,509 | -6,905 | -15,191 | -17,545 | -40,049 | -75,955 | -167,101 | -200,245 | -440,539 | -835,505 | -2,202,695 | -4,845,929 | -24,229,645 |
