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 1,395,845, 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 | 1,395,845 | |
| -1 | -1,395,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,395,845.
Example:
1 x 1,395,845 = 1,395,845
and
-1 x -1,395,845 = 1,395,845
Notice both answers equal 1,395,845
With that explanation out of the way, let's continue. Next, we take the number 1,395,845 and divide it by 2:
1,395,845 ÷ 2 = 697,922.5
If the quotient is a whole number, then 2 and 697,922.5 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 | 1,395,845 | |
| -1 | -1,395,845 |
Now, we try dividing 1,395,845 by 3:
1,395,845 ÷ 3 = 465,281.6667
If the quotient is a whole number, then 3 and 465,281.6667 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 | 1,395,845 | |
| -1 | -1,395,845 |
Let's try dividing by 4:
1,395,845 ÷ 4 = 348,961.25
If the quotient is a whole number, then 4 and 348,961.25 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 | 1,395,845 | |
| -1 | 1,395,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 41 | 55 | 205 | 451 | 619 | 2,255 | 3,095 | 6,809 | 25,379 | 34,045 | 126,895 | 279,169 | 1,395,845 |
| -1 | -5 | -11 | -41 | -55 | -205 | -451 | -619 | -2,255 | -3,095 | -6,809 | -25,379 | -34,045 | -126,895 | -279,169 | -1,395,845 |
