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 1,230,953, 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 | 1,230,953 | |
| -1 | -1,230,953 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,230,953.
Example:
1 x 1,230,953 = 1,230,953
and
-1 x -1,230,953 = 1,230,953
Notice both answers equal 1,230,953
With that explanation out of the way, let's continue. Next, we take the number 1,230,953 and divide it by 2:
1,230,953 ÷ 2 = 615,476.5
If the quotient is a whole number, then 2 and 615,476.5 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 | 1,230,953 | |
| -1 | -1,230,953 |
Now, we try dividing 1,230,953 by 3:
1,230,953 ÷ 3 = 410,317.6667
If the quotient is a whole number, then 3 and 410,317.6667 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 | 1,230,953 | |
| -1 | -1,230,953 |
Let's try dividing by 4:
1,230,953 ÷ 4 = 307,738.25
If the quotient is a whole number, then 4 and 307,738.25 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 | 1,230,953 | |
| -1 | 1,230,953 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 37 | 103 | 323 | 629 | 703 | 1,751 | 1,957 | 3,811 | 11,951 | 33,269 | 64,787 | 72,409 | 1,230,953 |
| -1 | -17 | -19 | -37 | -103 | -323 | -629 | -703 | -1,751 | -1,957 | -3,811 | -11,951 | -33,269 | -64,787 | -72,409 | -1,230,953 |
