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 38,513,825, 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 | 38,513,825 | |
| -1 | -38,513,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,513,825.
Example:
1 x 38,513,825 = 38,513,825
and
-1 x -38,513,825 = 38,513,825
Notice both answers equal 38,513,825
With that explanation out of the way, let's continue. Next, we take the number 38,513,825 and divide it by 2:
38,513,825 ÷ 2 = 19,256,912.5
If the quotient is a whole number, then 2 and 19,256,912.5 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 | 38,513,825 | |
| -1 | -38,513,825 |
Now, we try dividing 38,513,825 by 3:
38,513,825 ÷ 3 = 12,837,941.6667
If the quotient is a whole number, then 3 and 12,837,941.6667 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 | 38,513,825 | |
| -1 | -38,513,825 |
Let's try dividing by 4:
38,513,825 ÷ 4 = 9,628,456.25
If the quotient is a whole number, then 4 and 9,628,456.25 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 | 38,513,825 | |
| -1 | 38,513,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 101 | 175 | 505 | 707 | 2,179 | 2,525 | 3,535 | 10,895 | 15,253 | 17,675 | 54,475 | 76,265 | 220,079 | 381,325 | 1,100,395 | 1,540,553 | 5,501,975 | 7,702,765 | 38,513,825 |
| -1 | -5 | -7 | -25 | -35 | -101 | -175 | -505 | -707 | -2,179 | -2,525 | -3,535 | -10,895 | -15,253 | -17,675 | -54,475 | -76,265 | -220,079 | -381,325 | -1,100,395 | -1,540,553 | -5,501,975 | -7,702,765 | -38,513,825 |
