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 24,703,235, 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 | 24,703,235 | |
| -1 | -24,703,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,703,235.
Example:
1 x 24,703,235 = 24,703,235
and
-1 x -24,703,235 = 24,703,235
Notice both answers equal 24,703,235
With that explanation out of the way, let's continue. Next, we take the number 24,703,235 and divide it by 2:
24,703,235 ÷ 2 = 12,351,617.5
If the quotient is a whole number, then 2 and 12,351,617.5 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 | 24,703,235 | |
| -1 | -24,703,235 |
Now, we try dividing 24,703,235 by 3:
24,703,235 ÷ 3 = 8,234,411.6667
If the quotient is a whole number, then 3 and 8,234,411.6667 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 | 24,703,235 | |
| -1 | -24,703,235 |
Let's try dividing by 4:
24,703,235 ÷ 4 = 6,175,808.75
If the quotient is a whole number, then 4 and 6,175,808.75 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 | 24,703,235 | |
| -1 | 24,703,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 67 | 185 | 335 | 1,993 | 2,479 | 9,965 | 12,395 | 73,741 | 133,531 | 368,705 | 667,655 | 4,940,647 | 24,703,235 |
| -1 | -5 | -37 | -67 | -185 | -335 | -1,993 | -2,479 | -9,965 | -12,395 | -73,741 | -133,531 | -368,705 | -667,655 | -4,940,647 | -24,703,235 |
