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 44,078,111, 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 | 44,078,111 | |
| -1 | -44,078,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 44,078,111.
Example:
1 x 44,078,111 = 44,078,111
and
-1 x -44,078,111 = 44,078,111
Notice both answers equal 44,078,111
With that explanation out of the way, let's continue. Next, we take the number 44,078,111 and divide it by 2:
44,078,111 ÷ 2 = 22,039,055.5
If the quotient is a whole number, then 2 and 22,039,055.5 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 | 44,078,111 | |
| -1 | -44,078,111 |
Now, we try dividing 44,078,111 by 3:
44,078,111 ÷ 3 = 14,692,703.6667
If the quotient is a whole number, then 3 and 14,692,703.6667 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 | 44,078,111 | |
| -1 | -44,078,111 |
Let's try dividing by 4:
44,078,111 ÷ 4 = 11,019,527.75
If the quotient is a whole number, then 4 and 11,019,527.75 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 | 44,078,111 | |
| -1 | 44,078,111 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 211 | 1,477 | 2,321 | 2,713 | 16,247 | 18,991 | 29,843 | 208,901 | 572,443 | 4,007,101 | 6,296,873 | 44,078,111 |
| -1 | -7 | -11 | -77 | -211 | -1,477 | -2,321 | -2,713 | -16,247 | -18,991 | -29,843 | -208,901 | -572,443 | -4,007,101 | -6,296,873 | -44,078,111 |
