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 11,724,767, 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 | 11,724,767 | |
| -1 | -11,724,767 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,724,767.
Example:
1 x 11,724,767 = 11,724,767
and
-1 x -11,724,767 = 11,724,767
Notice both answers equal 11,724,767
With that explanation out of the way, let's continue. Next, we take the number 11,724,767 and divide it by 2:
11,724,767 ÷ 2 = 5,862,383.5
If the quotient is a whole number, then 2 and 5,862,383.5 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 | 11,724,767 | |
| -1 | -11,724,767 |
Now, we try dividing 11,724,767 by 3:
11,724,767 ÷ 3 = 3,908,255.6667
If the quotient is a whole number, then 3 and 3,908,255.6667 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 | 11,724,767 | |
| -1 | -11,724,767 |
Let's try dividing by 4:
11,724,767 ÷ 4 = 2,931,191.75
If the quotient is a whole number, then 4 and 2,931,191.75 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 | 11,724,767 | |
| -1 | 11,724,767 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 113 | 127 | 817 | 2,147 | 2,413 | 4,859 | 5,461 | 14,351 | 92,321 | 103,759 | 272,669 | 617,093 | 11,724,767 |
| -1 | -19 | -43 | -113 | -127 | -817 | -2,147 | -2,413 | -4,859 | -5,461 | -14,351 | -92,321 | -103,759 | -272,669 | -617,093 | -11,724,767 |
