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 3,800,825, 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 | 3,800,825 | |
| -1 | -3,800,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,800,825.
Example:
1 x 3,800,825 = 3,800,825
and
-1 x -3,800,825 = 3,800,825
Notice both answers equal 3,800,825
With that explanation out of the way, let's continue. Next, we take the number 3,800,825 and divide it by 2:
3,800,825 ÷ 2 = 1,900,412.5
If the quotient is a whole number, then 2 and 1,900,412.5 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 | 3,800,825 | |
| -1 | -3,800,825 |
Now, we try dividing 3,800,825 by 3:
3,800,825 ÷ 3 = 1,266,941.6667
If the quotient is a whole number, then 3 and 1,266,941.6667 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 | 3,800,825 | |
| -1 | -3,800,825 |
Let's try dividing by 4:
3,800,825 ÷ 4 = 950,206.25
If the quotient is a whole number, then 4 and 950,206.25 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 | 3,800,825 | |
| -1 | 3,800,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 37 | 175 | 185 | 259 | 587 | 925 | 1,295 | 2,935 | 4,109 | 6,475 | 14,675 | 20,545 | 21,719 | 102,725 | 108,595 | 152,033 | 542,975 | 760,165 | 3,800,825 |
| -1 | -5 | -7 | -25 | -35 | -37 | -175 | -185 | -259 | -587 | -925 | -1,295 | -2,935 | -4,109 | -6,475 | -14,675 | -20,545 | -21,719 | -102,725 | -108,595 | -152,033 | -542,975 | -760,165 | -3,800,825 |
