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 442,004,125, 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 | 442,004,125 | |
| -1 | -442,004,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 442,004,125.
Example:
1 x 442,004,125 = 442,004,125
and
-1 x -442,004,125 = 442,004,125
Notice both answers equal 442,004,125
With that explanation out of the way, let's continue. Next, we take the number 442,004,125 and divide it by 2:
442,004,125 ÷ 2 = 221,002,062.5
If the quotient is a whole number, then 2 and 221,002,062.5 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 | 442,004,125 | |
| -1 | -442,004,125 |
Now, we try dividing 442,004,125 by 3:
442,004,125 ÷ 3 = 147,334,708.3333
If the quotient is a whole number, then 3 and 147,334,708.3333 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 | 442,004,125 | |
| -1 | -442,004,125 |
Let's try dividing by 4:
442,004,125 ÷ 4 = 110,501,031.25
If the quotient is a whole number, then 4 and 110,501,031.25 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 | 442,004,125 | |
| -1 | 442,004,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 125 | 475 | 2,375 | 186,107 | 930,535 | 3,536,033 | 4,652,675 | 17,680,165 | 23,263,375 | 88,400,825 | 442,004,125 |
| -1 | -5 | -19 | -25 | -95 | -125 | -475 | -2,375 | -186,107 | -930,535 | -3,536,033 | -4,652,675 | -17,680,165 | -23,263,375 | -88,400,825 | -442,004,125 |
