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 3,486,785, 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 | 3,486,785 | |
| -1 | -3,486,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,486,785.
Example:
1 x 3,486,785 = 3,486,785
and
-1 x -3,486,785 = 3,486,785
Notice both answers equal 3,486,785
With that explanation out of the way, let's continue. Next, we take the number 3,486,785 and divide it by 2:
3,486,785 ÷ 2 = 1,743,392.5
If the quotient is a whole number, then 2 and 1,743,392.5 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 | 3,486,785 | |
| -1 | -3,486,785 |
Now, we try dividing 3,486,785 by 3:
3,486,785 ÷ 3 = 1,162,261.6667
If the quotient is a whole number, then 3 and 1,162,261.6667 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 | 3,486,785 | |
| -1 | -3,486,785 |
Let's try dividing by 4:
3,486,785 ÷ 4 = 871,696.25
If the quotient is a whole number, then 4 and 871,696.25 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 | 3,486,785 | |
| -1 | 3,486,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 85 | 95 | 127 | 289 | 323 | 635 | 1,445 | 1,615 | 2,159 | 2,413 | 5,491 | 10,795 | 12,065 | 27,455 | 36,703 | 41,021 | 183,515 | 205,105 | 697,357 | 3,486,785 |
| -1 | -5 | -17 | -19 | -85 | -95 | -127 | -289 | -323 | -635 | -1,445 | -1,615 | -2,159 | -2,413 | -5,491 | -10,795 | -12,065 | -27,455 | -36,703 | -41,021 | -183,515 | -205,105 | -697,357 | -3,486,785 |
