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 24,470,827, 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 | 24,470,827 | |
| -1 | -24,470,827 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,470,827.
Example:
1 x 24,470,827 = 24,470,827
and
-1 x -24,470,827 = 24,470,827
Notice both answers equal 24,470,827
With that explanation out of the way, let's continue. Next, we take the number 24,470,827 and divide it by 2:
24,470,827 ÷ 2 = 12,235,413.5
If the quotient is a whole number, then 2 and 12,235,413.5 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 | 24,470,827 | |
| -1 | -24,470,827 |
Now, we try dividing 24,470,827 by 3:
24,470,827 ÷ 3 = 8,156,942.3333
If the quotient is a whole number, then 3 and 8,156,942.3333 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 | 24,470,827 | |
| -1 | -24,470,827 |
Let's try dividing by 4:
24,470,827 ÷ 4 = 6,117,706.75
If the quotient is a whole number, then 4 and 6,117,706.75 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 | 24,470,827 | |
| -1 | 24,470,827 |
If you did it right, you will end up with this table:
| 1 | 23 | 43 | 109 | 227 | 989 | 2,507 | 4,687 | 5,221 | 9,761 | 24,743 | 107,801 | 224,503 | 569,089 | 1,063,949 | 24,470,827 |
| -1 | -23 | -43 | -109 | -227 | -989 | -2,507 | -4,687 | -5,221 | -9,761 | -24,743 | -107,801 | -224,503 | -569,089 | -1,063,949 | -24,470,827 |
