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 38,739,259, 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 | 38,739,259 | |
| -1 | -38,739,259 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,739,259.
Example:
1 x 38,739,259 = 38,739,259
and
-1 x -38,739,259 = 38,739,259
Notice both answers equal 38,739,259
With that explanation out of the way, let's continue. Next, we take the number 38,739,259 and divide it by 2:
38,739,259 ÷ 2 = 19,369,629.5
If the quotient is a whole number, then 2 and 19,369,629.5 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 | 38,739,259 | |
| -1 | -38,739,259 |
Now, we try dividing 38,739,259 by 3:
38,739,259 ÷ 3 = 12,913,086.3333
If the quotient is a whole number, then 3 and 12,913,086.3333 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 | 38,739,259 | |
| -1 | -38,739,259 |
Let's try dividing by 4:
38,739,259 ÷ 4 = 9,684,814.75
If the quotient is a whole number, then 4 and 9,684,814.75 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 | 38,739,259 | |
| -1 | 38,739,259 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 43 | 481 | 559 | 1,591 | 1,873 | 20,683 | 24,349 | 69,301 | 80,539 | 900,913 | 1,047,007 | 2,979,943 | 38,739,259 |
| -1 | -13 | -37 | -43 | -481 | -559 | -1,591 | -1,873 | -20,683 | -24,349 | -69,301 | -80,539 | -900,913 | -1,047,007 | -2,979,943 | -38,739,259 |
