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 1,254,125, 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 | 1,254,125 | |
| -1 | -1,254,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,254,125.
Example:
1 x 1,254,125 = 1,254,125
and
-1 x -1,254,125 = 1,254,125
Notice both answers equal 1,254,125
With that explanation out of the way, let's continue. Next, we take the number 1,254,125 and divide it by 2:
1,254,125 ÷ 2 = 627,062.5
If the quotient is a whole number, then 2 and 627,062.5 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 | 1,254,125 | |
| -1 | -1,254,125 |
Now, we try dividing 1,254,125 by 3:
1,254,125 ÷ 3 = 418,041.6667
If the quotient is a whole number, then 3 and 418,041.6667 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 | 1,254,125 | |
| -1 | -1,254,125 |
Let's try dividing by 4:
1,254,125 ÷ 4 = 313,531.25
If the quotient is a whole number, then 4 and 313,531.25 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 | 1,254,125 | |
| -1 | 1,254,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 79 | 125 | 127 | 395 | 635 | 1,975 | 3,175 | 9,875 | 10,033 | 15,875 | 50,165 | 250,825 | 1,254,125 |
| -1 | -5 | -25 | -79 | -125 | -127 | -395 | -635 | -1,975 | -3,175 | -9,875 | -10,033 | -15,875 | -50,165 | -250,825 | -1,254,125 |
