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 24,455,509, 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 | 24,455,509 | |
| -1 | -24,455,509 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,455,509.
Example:
1 x 24,455,509 = 24,455,509
and
-1 x -24,455,509 = 24,455,509
Notice both answers equal 24,455,509
With that explanation out of the way, let's continue. Next, we take the number 24,455,509 and divide it by 2:
24,455,509 ÷ 2 = 12,227,754.5
If the quotient is a whole number, then 2 and 12,227,754.5 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 | 24,455,509 | |
| -1 | -24,455,509 |
Now, we try dividing 24,455,509 by 3:
24,455,509 ÷ 3 = 8,151,836.3333
If the quotient is a whole number, then 3 and 8,151,836.3333 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 | 24,455,509 | |
| -1 | -24,455,509 |
Let's try dividing by 4:
24,455,509 ÷ 4 = 6,113,877.25
If the quotient is a whole number, then 4 and 6,113,877.25 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 | 24,455,509 | |
| -1 | 24,455,509 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 89 | 299 | 919 | 1,157 | 2,047 | 11,947 | 21,137 | 26,611 | 81,791 | 274,781 | 1,063,283 | 1,881,193 | 24,455,509 |
| -1 | -13 | -23 | -89 | -299 | -919 | -1,157 | -2,047 | -11,947 | -21,137 | -26,611 | -81,791 | -274,781 | -1,063,283 | -1,881,193 | -24,455,509 |
