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 4,252,625, 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 | 4,252,625 | |
| -1 | -4,252,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,252,625.
Example:
1 x 4,252,625 = 4,252,625
and
-1 x -4,252,625 = 4,252,625
Notice both answers equal 4,252,625
With that explanation out of the way, let's continue. Next, we take the number 4,252,625 and divide it by 2:
4,252,625 ÷ 2 = 2,126,312.5
If the quotient is a whole number, then 2 and 2,126,312.5 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 | 4,252,625 | |
| -1 | -4,252,625 |
Now, we try dividing 4,252,625 by 3:
4,252,625 ÷ 3 = 1,417,541.6667
If the quotient is a whole number, then 3 and 1,417,541.6667 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 | 4,252,625 | |
| -1 | -4,252,625 |
Let's try dividing by 4:
4,252,625 ÷ 4 = 1,063,156.25
If the quotient is a whole number, then 4 and 1,063,156.25 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 | 4,252,625 | |
| -1 | 4,252,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 1,625 | 2,617 | 13,085 | 34,021 | 65,425 | 170,105 | 327,125 | 850,525 | 4,252,625 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -1,625 | -2,617 | -13,085 | -34,021 | -65,425 | -170,105 | -327,125 | -850,525 | -4,252,625 |
