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 4,421,125, 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 | 4,421,125 | |
| -1 | -4,421,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,421,125.
Example:
1 x 4,421,125 = 4,421,125
and
-1 x -4,421,125 = 4,421,125
Notice both answers equal 4,421,125
With that explanation out of the way, let's continue. Next, we take the number 4,421,125 and divide it by 2:
4,421,125 ÷ 2 = 2,210,562.5
If the quotient is a whole number, then 2 and 2,210,562.5 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 | 4,421,125 | |
| -1 | -4,421,125 |
Now, we try dividing 4,421,125 by 3:
4,421,125 ÷ 3 = 1,473,708.3333
If the quotient is a whole number, then 3 and 1,473,708.3333 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 | 4,421,125 | |
| -1 | -4,421,125 |
Let's try dividing by 4:
4,421,125 ÷ 4 = 1,105,281.25
If the quotient is a whole number, then 4 and 1,105,281.25 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 | 4,421,125 | |
| -1 | 4,421,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 113 | 125 | 313 | 565 | 1,565 | 2,825 | 7,825 | 14,125 | 35,369 | 39,125 | 176,845 | 884,225 | 4,421,125 |
| -1 | -5 | -25 | -113 | -125 | -313 | -565 | -1,565 | -2,825 | -7,825 | -14,125 | -35,369 | -39,125 | -176,845 | -884,225 | -4,421,125 |
