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 1,244,495, 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 | 1,244,495 | |
| -1 | -1,244,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,244,495.
Example:
1 x 1,244,495 = 1,244,495
and
-1 x -1,244,495 = 1,244,495
Notice both answers equal 1,244,495
With that explanation out of the way, let's continue. Next, we take the number 1,244,495 and divide it by 2:
1,244,495 ÷ 2 = 622,247.5
If the quotient is a whole number, then 2 and 622,247.5 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 | 1,244,495 | |
| -1 | -1,244,495 |
Now, we try dividing 1,244,495 by 3:
1,244,495 ÷ 3 = 414,831.6667
If the quotient is a whole number, then 3 and 414,831.6667 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 | 1,244,495 | |
| -1 | -1,244,495 |
Let's try dividing by 4:
1,244,495 ÷ 4 = 311,123.75
If the quotient is a whole number, then 4 and 311,123.75 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 | 1,244,495 | |
| -1 | 1,244,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 37 | 155 | 185 | 217 | 259 | 961 | 1,085 | 1,147 | 1,295 | 4,805 | 5,735 | 6,727 | 8,029 | 33,635 | 35,557 | 40,145 | 177,785 | 248,899 | 1,244,495 |
| -1 | -5 | -7 | -31 | -35 | -37 | -155 | -185 | -217 | -259 | -961 | -1,085 | -1,147 | -1,295 | -4,805 | -5,735 | -6,727 | -8,029 | -33,635 | -35,557 | -40,145 | -177,785 | -248,899 | -1,244,495 |
