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 1,230,775, 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 | 1,230,775 | |
| -1 | -1,230,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,230,775.
Example:
1 x 1,230,775 = 1,230,775
and
-1 x -1,230,775 = 1,230,775
Notice both answers equal 1,230,775
With that explanation out of the way, let's continue. Next, we take the number 1,230,775 and divide it by 2:
1,230,775 ÷ 2 = 615,387.5
If the quotient is a whole number, then 2 and 615,387.5 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 | 1,230,775 | |
| -1 | -1,230,775 |
Now, we try dividing 1,230,775 by 3:
1,230,775 ÷ 3 = 410,258.3333
If the quotient is a whole number, then 3 and 410,258.3333 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 | 1,230,775 | |
| -1 | -1,230,775 |
Let's try dividing by 4:
1,230,775 ÷ 4 = 307,693.75
If the quotient is a whole number, then 4 and 307,693.75 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 | 1,230,775 | |
| -1 | 1,230,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 25 | 35 | 65 | 91 | 175 | 325 | 455 | 541 | 2,275 | 2,705 | 3,787 | 7,033 | 13,525 | 18,935 | 35,165 | 49,231 | 94,675 | 175,825 | 246,155 | 1,230,775 |
| -1 | -5 | -7 | -13 | -25 | -35 | -65 | -91 | -175 | -325 | -455 | -541 | -2,275 | -2,705 | -3,787 | -7,033 | -13,525 | -18,935 | -35,165 | -49,231 | -94,675 | -175,825 | -246,155 | -1,230,775 |
