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 3,825,875, 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 | 3,825,875 | |
| -1 | -3,825,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,825,875.
Example:
1 x 3,825,875 = 3,825,875
and
-1 x -3,825,875 = 3,825,875
Notice both answers equal 3,825,875
With that explanation out of the way, let's continue. Next, we take the number 3,825,875 and divide it by 2:
3,825,875 ÷ 2 = 1,912,937.5
If the quotient is a whole number, then 2 and 1,912,937.5 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 | 3,825,875 | |
| -1 | -3,825,875 |
Now, we try dividing 3,825,875 by 3:
3,825,875 ÷ 3 = 1,275,291.6667
If the quotient is a whole number, then 3 and 1,275,291.6667 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 | 3,825,875 | |
| -1 | -3,825,875 |
Let's try dividing by 4:
3,825,875 ÷ 4 = 956,468.75
If the quotient is a whole number, then 4 and 956,468.75 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 | 3,825,875 | |
| -1 | 3,825,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 127 | 241 | 635 | 1,205 | 3,175 | 6,025 | 15,875 | 30,125 | 30,607 | 153,035 | 765,175 | 3,825,875 |
| -1 | -5 | -25 | -125 | -127 | -241 | -635 | -1,205 | -3,175 | -6,025 | -15,875 | -30,125 | -30,607 | -153,035 | -765,175 | -3,825,875 |
