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 38,463,599, 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 | 38,463,599 | |
| -1 | -38,463,599 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,463,599.
Example:
1 x 38,463,599 = 38,463,599
and
-1 x -38,463,599 = 38,463,599
Notice both answers equal 38,463,599
With that explanation out of the way, let's continue. Next, we take the number 38,463,599 and divide it by 2:
38,463,599 ÷ 2 = 19,231,799.5
If the quotient is a whole number, then 2 and 19,231,799.5 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 | 38,463,599 | |
| -1 | -38,463,599 |
Now, we try dividing 38,463,599 by 3:
38,463,599 ÷ 3 = 12,821,199.6667
If the quotient is a whole number, then 3 and 12,821,199.6667 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 | 38,463,599 | |
| -1 | -38,463,599 |
Let's try dividing by 4:
38,463,599 ÷ 4 = 9,615,899.75
If the quotient is a whole number, then 4 and 9,615,899.75 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 | 38,463,599 | |
| -1 | 38,463,599 |
If you did it right, you will end up with this table:
| 1 | 29 | 79 | 103 | 163 | 2,291 | 2,987 | 4,727 | 8,137 | 12,877 | 16,789 | 235,973 | 373,433 | 486,881 | 1,326,331 | 38,463,599 |
| -1 | -29 | -79 | -103 | -163 | -2,291 | -2,987 | -4,727 | -8,137 | -12,877 | -16,789 | -235,973 | -373,433 | -486,881 | -1,326,331 | -38,463,599 |
