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 1,755,505, 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 | 1,755,505 | |
| -1 | -1,755,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,755,505.
Example:
1 x 1,755,505 = 1,755,505
and
-1 x -1,755,505 = 1,755,505
Notice both answers equal 1,755,505
With that explanation out of the way, let's continue. Next, we take the number 1,755,505 and divide it by 2:
1,755,505 ÷ 2 = 877,752.5
If the quotient is a whole number, then 2 and 877,752.5 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 | 1,755,505 | |
| -1 | -1,755,505 |
Now, we try dividing 1,755,505 by 3:
1,755,505 ÷ 3 = 585,168.3333
If the quotient is a whole number, then 3 and 585,168.3333 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 | 1,755,505 | |
| -1 | -1,755,505 |
Let's try dividing by 4:
1,755,505 ÷ 4 = 438,876.25
If the quotient is a whole number, then 4 and 438,876.25 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 | 1,755,505 | |
| -1 | 1,755,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 85 | 95 | 323 | 1,087 | 1,615 | 5,435 | 18,479 | 20,653 | 92,395 | 103,265 | 351,101 | 1,755,505 |
| -1 | -5 | -17 | -19 | -85 | -95 | -323 | -1,087 | -1,615 | -5,435 | -18,479 | -20,653 | -92,395 | -103,265 | -351,101 | -1,755,505 |
