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 28,818,383, 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 | 28,818,383 | |
| -1 | -28,818,383 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,818,383.
Example:
1 x 28,818,383 = 28,818,383
and
-1 x -28,818,383 = 28,818,383
Notice both answers equal 28,818,383
With that explanation out of the way, let's continue. Next, we take the number 28,818,383 and divide it by 2:
28,818,383 ÷ 2 = 14,409,191.5
If the quotient is a whole number, then 2 and 14,409,191.5 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 | 28,818,383 | |
| -1 | -28,818,383 |
Now, we try dividing 28,818,383 by 3:
28,818,383 ÷ 3 = 9,606,127.6667
If the quotient is a whole number, then 3 and 9,606,127.6667 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 | 28,818,383 | |
| -1 | -28,818,383 |
Let's try dividing by 4:
28,818,383 ÷ 4 = 7,204,595.75
If the quotient is a whole number, then 4 and 7,204,595.75 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 | 28,818,383 | |
| -1 | 28,818,383 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 19 | 187 | 209 | 323 | 3,553 | 8,111 | 89,221 | 137,887 | 154,109 | 1,516,757 | 1,695,199 | 2,619,853 | 28,818,383 |
| -1 | -11 | -17 | -19 | -187 | -209 | -323 | -3,553 | -8,111 | -89,221 | -137,887 | -154,109 | -1,516,757 | -1,695,199 | -2,619,853 | -28,818,383 |
