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 1,391,435, 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 | 1,391,435 | |
| -1 | -1,391,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,391,435.
Example:
1 x 1,391,435 = 1,391,435
and
-1 x -1,391,435 = 1,391,435
Notice both answers equal 1,391,435
With that explanation out of the way, let's continue. Next, we take the number 1,391,435 and divide it by 2:
1,391,435 ÷ 2 = 695,717.5
If the quotient is a whole number, then 2 and 695,717.5 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 | 1,391,435 | |
| -1 | -1,391,435 |
Now, we try dividing 1,391,435 by 3:
1,391,435 ÷ 3 = 463,811.6667
If the quotient is a whole number, then 3 and 463,811.6667 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 | 1,391,435 | |
| -1 | -1,391,435 |
Let's try dividing by 4:
1,391,435 ÷ 4 = 347,858.75
If the quotient is a whole number, then 4 and 347,858.75 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 | 1,391,435 | |
| -1 | 1,391,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 47 | 155 | 191 | 235 | 955 | 1,457 | 5,921 | 7,285 | 8,977 | 29,605 | 44,885 | 278,287 | 1,391,435 |
| -1 | -5 | -31 | -47 | -155 | -191 | -235 | -955 | -1,457 | -5,921 | -7,285 | -8,977 | -29,605 | -44,885 | -278,287 | -1,391,435 |
