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 24,710,465, 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 | 24,710,465 | |
| -1 | -24,710,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,710,465.
Example:
1 x 24,710,465 = 24,710,465
and
-1 x -24,710,465 = 24,710,465
Notice both answers equal 24,710,465
With that explanation out of the way, let's continue. Next, we take the number 24,710,465 and divide it by 2:
24,710,465 ÷ 2 = 12,355,232.5
If the quotient is a whole number, then 2 and 12,355,232.5 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 | 24,710,465 | |
| -1 | -24,710,465 |
Now, we try dividing 24,710,465 by 3:
24,710,465 ÷ 3 = 8,236,821.6667
If the quotient is a whole number, then 3 and 8,236,821.6667 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 | 24,710,465 | |
| -1 | -24,710,465 |
Let's try dividing by 4:
24,710,465 ÷ 4 = 6,177,616.25
If the quotient is a whole number, then 4 and 6,177,616.25 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 | 24,710,465 | |
| -1 | 24,710,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 29 | 65 | 145 | 377 | 1,885 | 13,109 | 65,545 | 170,417 | 380,161 | 852,085 | 1,900,805 | 4,942,093 | 24,710,465 |
| -1 | -5 | -13 | -29 | -65 | -145 | -377 | -1,885 | -13,109 | -65,545 | -170,417 | -380,161 | -852,085 | -1,900,805 | -4,942,093 | -24,710,465 |
