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 11,277,875, 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 | 11,277,875 | |
| -1 | -11,277,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,277,875.
Example:
1 x 11,277,875 = 11,277,875
and
-1 x -11,277,875 = 11,277,875
Notice both answers equal 11,277,875
With that explanation out of the way, let's continue. Next, we take the number 11,277,875 and divide it by 2:
11,277,875 ÷ 2 = 5,638,937.5
If the quotient is a whole number, then 2 and 5,638,937.5 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 | 11,277,875 | |
| -1 | -11,277,875 |
Now, we try dividing 11,277,875 by 3:
11,277,875 ÷ 3 = 3,759,291.6667
If the quotient is a whole number, then 3 and 3,759,291.6667 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 | 11,277,875 | |
| -1 | -11,277,875 |
Let's try dividing by 4:
11,277,875 ÷ 4 = 2,819,468.75
If the quotient is a whole number, then 4 and 2,819,468.75 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 | 11,277,875 | |
| -1 | 11,277,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 12,889 | 64,445 | 90,223 | 322,225 | 451,115 | 1,611,125 | 2,255,575 | 11,277,875 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -12,889 | -64,445 | -90,223 | -322,225 | -451,115 | -1,611,125 | -2,255,575 | -11,277,875 |
