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 38,027,483, 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 | 38,027,483 | |
| -1 | -38,027,483 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,027,483.
Example:
1 x 38,027,483 = 38,027,483
and
-1 x -38,027,483 = 38,027,483
Notice both answers equal 38,027,483
With that explanation out of the way, let's continue. Next, we take the number 38,027,483 and divide it by 2:
38,027,483 ÷ 2 = 19,013,741.5
If the quotient is a whole number, then 2 and 19,013,741.5 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 | 38,027,483 | |
| -1 | -38,027,483 |
Now, we try dividing 38,027,483 by 3:
38,027,483 ÷ 3 = 12,675,827.6667
If the quotient is a whole number, then 3 and 12,675,827.6667 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 | 38,027,483 | |
| -1 | -38,027,483 |
Let's try dividing by 4:
38,027,483 ÷ 4 = 9,506,870.75
If the quotient is a whole number, then 4 and 9,506,870.75 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 | 38,027,483 | |
| -1 | 38,027,483 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 127 | 403 | 743 | 1,651 | 3,937 | 9,659 | 23,033 | 51,181 | 94,361 | 299,429 | 1,226,693 | 2,925,191 | 38,027,483 |
| -1 | -13 | -31 | -127 | -403 | -743 | -1,651 | -3,937 | -9,659 | -23,033 | -51,181 | -94,361 | -299,429 | -1,226,693 | -2,925,191 | -38,027,483 |
