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 3,401,531, 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 | 3,401,531 | |
| -1 | -3,401,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,401,531.
Example:
1 x 3,401,531 = 3,401,531
and
-1 x -3,401,531 = 3,401,531
Notice both answers equal 3,401,531
With that explanation out of the way, let's continue. Next, we take the number 3,401,531 and divide it by 2:
3,401,531 ÷ 2 = 1,700,765.5
If the quotient is a whole number, then 2 and 1,700,765.5 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 | 3,401,531 | |
| -1 | -3,401,531 |
Now, we try dividing 3,401,531 by 3:
3,401,531 ÷ 3 = 1,133,843.6667
If the quotient is a whole number, then 3 and 1,133,843.6667 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 | 3,401,531 | |
| -1 | -3,401,531 |
Let's try dividing by 4:
3,401,531 ÷ 4 = 850,382.75
If the quotient is a whole number, then 4 and 850,382.75 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 | 3,401,531 | |
| -1 | 3,401,531 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 49 | 211 | 329 | 343 | 1,477 | 2,303 | 9,917 | 10,339 | 16,121 | 69,419 | 72,373 | 485,933 | 3,401,531 |
| -1 | -7 | -47 | -49 | -211 | -329 | -343 | -1,477 | -2,303 | -9,917 | -10,339 | -16,121 | -69,419 | -72,373 | -485,933 | -3,401,531 |
