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 24,703,553, 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 | 24,703,553 | |
| -1 | -24,703,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,703,553.
Example:
1 x 24,703,553 = 24,703,553
and
-1 x -24,703,553 = 24,703,553
Notice both answers equal 24,703,553
With that explanation out of the way, let's continue. Next, we take the number 24,703,553 and divide it by 2:
24,703,553 ÷ 2 = 12,351,776.5
If the quotient is a whole number, then 2 and 12,351,776.5 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 | 24,703,553 | |
| -1 | -24,703,553 |
Now, we try dividing 24,703,553 by 3:
24,703,553 ÷ 3 = 8,234,517.6667
If the quotient is a whole number, then 3 and 8,234,517.6667 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 | 24,703,553 | |
| -1 | -24,703,553 |
Let's try dividing by 4:
24,703,553 ÷ 4 = 6,175,888.25
If the quotient is a whole number, then 4 and 6,175,888.25 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 | 24,703,553 | |
| -1 | 24,703,553 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 281 | 661 | 1,967 | 4,627 | 5,339 | 12,559 | 37,373 | 87,913 | 185,741 | 1,300,187 | 3,529,079 | 24,703,553 |
| -1 | -7 | -19 | -133 | -281 | -661 | -1,967 | -4,627 | -5,339 | -12,559 | -37,373 | -87,913 | -185,741 | -1,300,187 | -3,529,079 | -24,703,553 |
