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 24,573,715, 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 | 24,573,715 | |
| -1 | -24,573,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,573,715.
Example:
1 x 24,573,715 = 24,573,715
and
-1 x -24,573,715 = 24,573,715
Notice both answers equal 24,573,715
With that explanation out of the way, let's continue. Next, we take the number 24,573,715 and divide it by 2:
24,573,715 ÷ 2 = 12,286,857.5
If the quotient is a whole number, then 2 and 12,286,857.5 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 | 24,573,715 | |
| -1 | -24,573,715 |
Now, we try dividing 24,573,715 by 3:
24,573,715 ÷ 3 = 8,191,238.3333
If the quotient is a whole number, then 3 and 8,191,238.3333 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 | 24,573,715 | |
| -1 | -24,573,715 |
Let's try dividing by 4:
24,573,715 ÷ 4 = 6,143,428.75
If the quotient is a whole number, then 4 and 6,143,428.75 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 | 24,573,715 | |
| -1 | 24,573,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 53 | 235 | 265 | 1,973 | 2,491 | 9,865 | 12,455 | 92,731 | 104,569 | 463,655 | 522,845 | 4,914,743 | 24,573,715 |
| -1 | -5 | -47 | -53 | -235 | -265 | -1,973 | -2,491 | -9,865 | -12,455 | -92,731 | -104,569 | -463,655 | -522,845 | -4,914,743 | -24,573,715 |
