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 1,724,125, 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 | 1,724,125 | |
| -1 | -1,724,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,724,125.
Example:
1 x 1,724,125 = 1,724,125
and
-1 x -1,724,125 = 1,724,125
Notice both answers equal 1,724,125
With that explanation out of the way, let's continue. Next, we take the number 1,724,125 and divide it by 2:
1,724,125 ÷ 2 = 862,062.5
If the quotient is a whole number, then 2 and 862,062.5 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 | 1,724,125 | |
| -1 | -1,724,125 |
Now, we try dividing 1,724,125 by 3:
1,724,125 ÷ 3 = 574,708.3333
If the quotient is a whole number, then 3 and 574,708.3333 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 | 1,724,125 | |
| -1 | -1,724,125 |
Let's try dividing by 4:
1,724,125 ÷ 4 = 431,031.25
If the quotient is a whole number, then 4 and 431,031.25 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 | 1,724,125 | |
| -1 | 1,724,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 1,061 | 1,625 | 5,305 | 13,793 | 26,525 | 68,965 | 132,625 | 344,825 | 1,724,125 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -1,061 | -1,625 | -5,305 | -13,793 | -26,525 | -68,965 | -132,625 | -344,825 | -1,724,125 |
