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 1,758,785, 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 | 1,758,785 | |
| -1 | -1,758,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,758,785.
Example:
1 x 1,758,785 = 1,758,785
and
-1 x -1,758,785 = 1,758,785
Notice both answers equal 1,758,785
With that explanation out of the way, let's continue. Next, we take the number 1,758,785 and divide it by 2:
1,758,785 ÷ 2 = 879,392.5
If the quotient is a whole number, then 2 and 879,392.5 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 | 1,758,785 | |
| -1 | -1,758,785 |
Now, we try dividing 1,758,785 by 3:
1,758,785 ÷ 3 = 586,261.6667
If the quotient is a whole number, then 3 and 586,261.6667 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 | 1,758,785 | |
| -1 | -1,758,785 |
Let's try dividing by 4:
1,758,785 ÷ 4 = 439,696.25
If the quotient is a whole number, then 4 and 439,696.25 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 | 1,758,785 | |
| -1 | 1,758,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 1,621 | 8,105 | 11,347 | 50,251 | 56,735 | 251,255 | 351,757 | 1,758,785 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -1,621 | -8,105 | -11,347 | -50,251 | -56,735 | -251,255 | -351,757 | -1,758,785 |
