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 11,424,215, 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 | 11,424,215 | |
| -1 | -11,424,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,424,215.
Example:
1 x 11,424,215 = 11,424,215
and
-1 x -11,424,215 = 11,424,215
Notice both answers equal 11,424,215
With that explanation out of the way, let's continue. Next, we take the number 11,424,215 and divide it by 2:
11,424,215 ÷ 2 = 5,712,107.5
If the quotient is a whole number, then 2 and 5,712,107.5 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 | 11,424,215 | |
| -1 | -11,424,215 |
Now, we try dividing 11,424,215 by 3:
11,424,215 ÷ 3 = 3,808,071.6667
If the quotient is a whole number, then 3 and 3,808,071.6667 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 | 11,424,215 | |
| -1 | -11,424,215 |
Let's try dividing by 4:
11,424,215 ÷ 4 = 2,856,053.75
If the quotient is a whole number, then 4 and 2,856,053.75 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 | 11,424,215 | |
| -1 | 11,424,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 121 | 253 | 605 | 821 | 1,265 | 2,783 | 4,105 | 9,031 | 13,915 | 18,883 | 45,155 | 94,415 | 99,341 | 207,713 | 496,705 | 1,038,565 | 2,284,843 | 11,424,215 |
| -1 | -5 | -11 | -23 | -55 | -115 | -121 | -253 | -605 | -821 | -1,265 | -2,783 | -4,105 | -9,031 | -13,915 | -18,883 | -45,155 | -94,415 | -99,341 | -207,713 | -496,705 | -1,038,565 | -2,284,843 | -11,424,215 |
