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 1,435,511, 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 | 1,435,511 | |
| -1 | -1,435,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,435,511.
Example:
1 x 1,435,511 = 1,435,511
and
-1 x -1,435,511 = 1,435,511
Notice both answers equal 1,435,511
With that explanation out of the way, let's continue. Next, we take the number 1,435,511 and divide it by 2:
1,435,511 ÷ 2 = 717,755.5
If the quotient is a whole number, then 2 and 717,755.5 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 | 1,435,511 | |
| -1 | -1,435,511 |
Now, we try dividing 1,435,511 by 3:
1,435,511 ÷ 3 = 478,503.6667
If the quotient is a whole number, then 3 and 478,503.6667 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 | 1,435,511 | |
| -1 | -1,435,511 |
Let's try dividing by 4:
1,435,511 ÷ 4 = 358,877.75
If the quotient is a whole number, then 4 and 358,877.75 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 | 1,435,511 | |
| -1 | 1,435,511 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 103 | 181 | 721 | 1,133 | 1,267 | 1,991 | 7,931 | 13,937 | 18,643 | 130,501 | 205,073 | 1,435,511 |
| -1 | -7 | -11 | -77 | -103 | -181 | -721 | -1,133 | -1,267 | -1,991 | -7,931 | -13,937 | -18,643 | -130,501 | -205,073 | -1,435,511 |
