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 1,661,335, 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 | 1,661,335 | |
| -1 | -1,661,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,661,335.
Example:
1 x 1,661,335 = 1,661,335
and
-1 x -1,661,335 = 1,661,335
Notice both answers equal 1,661,335
With that explanation out of the way, let's continue. Next, we take the number 1,661,335 and divide it by 2:
1,661,335 ÷ 2 = 830,667.5
If the quotient is a whole number, then 2 and 830,667.5 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 | 1,661,335 | |
| -1 | -1,661,335 |
Now, we try dividing 1,661,335 by 3:
1,661,335 ÷ 3 = 553,778.3333
If the quotient is a whole number, then 3 and 553,778.3333 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 | 1,661,335 | |
| -1 | -1,661,335 |
Let's try dividing by 4:
1,661,335 ÷ 4 = 415,333.75
If the quotient is a whole number, then 4 and 415,333.75 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 | 1,661,335 | |
| -1 | 1,661,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 61 | 65 | 305 | 419 | 793 | 2,095 | 3,965 | 5,447 | 25,559 | 27,235 | 127,795 | 332,267 | 1,661,335 |
| -1 | -5 | -13 | -61 | -65 | -305 | -419 | -793 | -2,095 | -3,965 | -5,447 | -25,559 | -27,235 | -127,795 | -332,267 | -1,661,335 |
