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 1,231,195, 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 | 1,231,195 | |
| -1 | -1,231,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,231,195.
Example:
1 x 1,231,195 = 1,231,195
and
-1 x -1,231,195 = 1,231,195
Notice both answers equal 1,231,195
With that explanation out of the way, let's continue. Next, we take the number 1,231,195 and divide it by 2:
1,231,195 ÷ 2 = 615,597.5
If the quotient is a whole number, then 2 and 615,597.5 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 | 1,231,195 | |
| -1 | -1,231,195 |
Now, we try dividing 1,231,195 by 3:
1,231,195 ÷ 3 = 410,398.3333
If the quotient is a whole number, then 3 and 410,398.3333 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 | 1,231,195 | |
| -1 | -1,231,195 |
Let's try dividing by 4:
1,231,195 ÷ 4 = 307,798.75
If the quotient is a whole number, then 4 and 307,798.75 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 | 1,231,195 | |
| -1 | 1,231,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 1,213 | 6,065 | 8,491 | 35,177 | 42,455 | 175,885 | 246,239 | 1,231,195 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -1,213 | -6,065 | -8,491 | -35,177 | -42,455 | -175,885 | -246,239 | -1,231,195 |
