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 38,814,383, 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 | 38,814,383 | |
| -1 | -38,814,383 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,814,383.
Example:
1 x 38,814,383 = 38,814,383
and
-1 x -38,814,383 = 38,814,383
Notice both answers equal 38,814,383
With that explanation out of the way, let's continue. Next, we take the number 38,814,383 and divide it by 2:
38,814,383 ÷ 2 = 19,407,191.5
If the quotient is a whole number, then 2 and 19,407,191.5 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 | 38,814,383 | |
| -1 | -38,814,383 |
Now, we try dividing 38,814,383 by 3:
38,814,383 ÷ 3 = 12,938,127.6667
If the quotient is a whole number, then 3 and 12,938,127.6667 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 | 38,814,383 | |
| -1 | -38,814,383 |
Let's try dividing by 4:
38,814,383 ÷ 4 = 9,703,595.75
If the quotient is a whole number, then 4 and 9,703,595.75 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 | 38,814,383 | |
| -1 | 38,814,383 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 131 | 493 | 601 | 2,227 | 3,799 | 10,217 | 17,429 | 64,583 | 78,731 | 296,293 | 1,338,427 | 2,283,199 | 38,814,383 |
| -1 | -17 | -29 | -131 | -493 | -601 | -2,227 | -3,799 | -10,217 | -17,429 | -64,583 | -78,731 | -296,293 | -1,338,427 | -2,283,199 | -38,814,383 |
