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 24,509,651, 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 | 24,509,651 | |
| -1 | -24,509,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,509,651.
Example:
1 x 24,509,651 = 24,509,651
and
-1 x -24,509,651 = 24,509,651
Notice both answers equal 24,509,651
With that explanation out of the way, let's continue. Next, we take the number 24,509,651 and divide it by 2:
24,509,651 ÷ 2 = 12,254,825.5
If the quotient is a whole number, then 2 and 12,254,825.5 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 | 24,509,651 | |
| -1 | -24,509,651 |
Now, we try dividing 24,509,651 by 3:
24,509,651 ÷ 3 = 8,169,883.6667
If the quotient is a whole number, then 3 and 8,169,883.6667 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 | 24,509,651 | |
| -1 | -24,509,651 |
Let's try dividing by 4:
24,509,651 ÷ 4 = 6,127,412.75
If the quotient is a whole number, then 4 and 6,127,412.75 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 | 24,509,651 | |
| -1 | 24,509,651 |
If you did it right, you will end up with this table:
| 1 | 23 | 37 | 83 | 347 | 851 | 1,909 | 3,071 | 7,981 | 12,839 | 28,801 | 70,633 | 295,297 | 662,423 | 1,065,637 | 24,509,651 |
| -1 | -23 | -37 | -83 | -347 | -851 | -1,909 | -3,071 | -7,981 | -12,839 | -28,801 | -70,633 | -295,297 | -662,423 | -1,065,637 | -24,509,651 |
