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 3,491,705, 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 | 3,491,705 | |
| -1 | -3,491,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,491,705.
Example:
1 x 3,491,705 = 3,491,705
and
-1 x -3,491,705 = 3,491,705
Notice both answers equal 3,491,705
With that explanation out of the way, let's continue. Next, we take the number 3,491,705 and divide it by 2:
3,491,705 ÷ 2 = 1,745,852.5
If the quotient is a whole number, then 2 and 1,745,852.5 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 | 3,491,705 | |
| -1 | -3,491,705 |
Now, we try dividing 3,491,705 by 3:
3,491,705 ÷ 3 = 1,163,901.6667
If the quotient is a whole number, then 3 and 1,163,901.6667 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 | 3,491,705 | |
| -1 | -3,491,705 |
Let's try dividing by 4:
3,491,705 ÷ 4 = 872,926.25
If the quotient is a whole number, then 4 and 872,926.25 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 | 3,491,705 | |
| -1 | 3,491,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 67 | 335 | 469 | 1,489 | 2,345 | 7,445 | 10,423 | 52,115 | 99,763 | 498,815 | 698,341 | 3,491,705 |
| -1 | -5 | -7 | -35 | -67 | -335 | -469 | -1,489 | -2,345 | -7,445 | -10,423 | -52,115 | -99,763 | -498,815 | -698,341 | -3,491,705 |
