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 3,316,643, 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 | 3,316,643 | |
| -1 | -3,316,643 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,316,643.
Example:
1 x 3,316,643 = 3,316,643
and
-1 x -3,316,643 = 3,316,643
Notice both answers equal 3,316,643
With that explanation out of the way, let's continue. Next, we take the number 3,316,643 and divide it by 2:
3,316,643 ÷ 2 = 1,658,321.5
If the quotient is a whole number, then 2 and 1,658,321.5 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 | 3,316,643 | |
| -1 | -3,316,643 |
Now, we try dividing 3,316,643 by 3:
3,316,643 ÷ 3 = 1,105,547.6667
If the quotient is a whole number, then 3 and 1,105,547.6667 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 | 3,316,643 | |
| -1 | -3,316,643 |
Let's try dividing by 4:
3,316,643 ÷ 4 = 829,160.75
If the quotient is a whole number, then 4 and 829,160.75 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 | 3,316,643 | |
| -1 | 3,316,643 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 37 | 281 | 319 | 407 | 1,073 | 3,091 | 8,149 | 10,397 | 11,803 | 89,639 | 114,367 | 301,513 | 3,316,643 |
| -1 | -11 | -29 | -37 | -281 | -319 | -407 | -1,073 | -3,091 | -8,149 | -10,397 | -11,803 | -89,639 | -114,367 | -301,513 | -3,316,643 |
