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 1,244,635, 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 | 1,244,635 | |
| -1 | -1,244,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,244,635.
Example:
1 x 1,244,635 = 1,244,635
and
-1 x -1,244,635 = 1,244,635
Notice both answers equal 1,244,635
With that explanation out of the way, let's continue. Next, we take the number 1,244,635 and divide it by 2:
1,244,635 ÷ 2 = 622,317.5
If the quotient is a whole number, then 2 and 622,317.5 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 | 1,244,635 | |
| -1 | -1,244,635 |
Now, we try dividing 1,244,635 by 3:
1,244,635 ÷ 3 = 414,878.3333
If the quotient is a whole number, then 3 and 414,878.3333 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 | 1,244,635 | |
| -1 | -1,244,635 |
Let's try dividing by 4:
1,244,635 ÷ 4 = 311,158.75
If the quotient is a whole number, then 4 and 311,158.75 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 | 1,244,635 | |
| -1 | 1,244,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 827 | 1,505 | 4,135 | 5,789 | 28,945 | 35,561 | 177,805 | 248,927 | 1,244,635 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -827 | -1,505 | -4,135 | -5,789 | -28,945 | -35,561 | -177,805 | -248,927 | -1,244,635 |
