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 3,164,317, 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 | 3,164,317 | |
| -1 | -3,164,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,164,317.
Example:
1 x 3,164,317 = 3,164,317
and
-1 x -3,164,317 = 3,164,317
Notice both answers equal 3,164,317
With that explanation out of the way, let's continue. Next, we take the number 3,164,317 and divide it by 2:
3,164,317 ÷ 2 = 1,582,158.5
If the quotient is a whole number, then 2 and 1,582,158.5 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 | 3,164,317 | |
| -1 | -3,164,317 |
Now, we try dividing 3,164,317 by 3:
3,164,317 ÷ 3 = 1,054,772.3333
If the quotient is a whole number, then 3 and 1,054,772.3333 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 | 3,164,317 | |
| -1 | -3,164,317 |
Let's try dividing by 4:
3,164,317 ÷ 4 = 791,079.25
If the quotient is a whole number, then 4 and 791,079.25 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 | 3,164,317 | |
| -1 | 3,164,317 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 23 | 247 | 299 | 437 | 557 | 5,681 | 7,241 | 10,583 | 12,811 | 137,579 | 166,543 | 243,409 | 3,164,317 |
| -1 | -13 | -19 | -23 | -247 | -299 | -437 | -557 | -5,681 | -7,241 | -10,583 | -12,811 | -137,579 | -166,543 | -243,409 | -3,164,317 |
