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 1,396,885, 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 | 1,396,885 | |
| -1 | -1,396,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,396,885.
Example:
1 x 1,396,885 = 1,396,885
and
-1 x -1,396,885 = 1,396,885
Notice both answers equal 1,396,885
With that explanation out of the way, let's continue. Next, we take the number 1,396,885 and divide it by 2:
1,396,885 ÷ 2 = 698,442.5
If the quotient is a whole number, then 2 and 698,442.5 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 | 1,396,885 | |
| -1 | -1,396,885 |
Now, we try dividing 1,396,885 by 3:
1,396,885 ÷ 3 = 465,628.3333
If the quotient is a whole number, then 3 and 465,628.3333 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 | 1,396,885 | |
| -1 | -1,396,885 |
Let's try dividing by 4:
1,396,885 ÷ 4 = 349,221.25
If the quotient is a whole number, then 4 and 349,221.25 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 | 1,396,885 | |
| -1 | 1,396,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 107 | 373 | 535 | 749 | 1,865 | 2,611 | 3,745 | 13,055 | 39,911 | 199,555 | 279,377 | 1,396,885 |
| -1 | -5 | -7 | -35 | -107 | -373 | -535 | -749 | -1,865 | -2,611 | -3,745 | -13,055 | -39,911 | -199,555 | -279,377 | -1,396,885 |
