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 3,398,185, 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 | 3,398,185 | |
| -1 | -3,398,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,398,185.
Example:
1 x 3,398,185 = 3,398,185
and
-1 x -3,398,185 = 3,398,185
Notice both answers equal 3,398,185
With that explanation out of the way, let's continue. Next, we take the number 3,398,185 and divide it by 2:
3,398,185 ÷ 2 = 1,699,092.5
If the quotient is a whole number, then 2 and 1,699,092.5 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 | 3,398,185 | |
| -1 | -3,398,185 |
Now, we try dividing 3,398,185 by 3:
3,398,185 ÷ 3 = 1,132,728.3333
If the quotient is a whole number, then 3 and 1,132,728.3333 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 | 3,398,185 | |
| -1 | -3,398,185 |
Let's try dividing by 4:
3,398,185 ÷ 4 = 849,546.25
If the quotient is a whole number, then 4 and 849,546.25 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 | 3,398,185 | |
| -1 | 3,398,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 79 | 395 | 553 | 1,229 | 2,765 | 6,145 | 8,603 | 43,015 | 97,091 | 485,455 | 679,637 | 3,398,185 |
| -1 | -5 | -7 | -35 | -79 | -395 | -553 | -1,229 | -2,765 | -6,145 | -8,603 | -43,015 | -97,091 | -485,455 | -679,637 | -3,398,185 |
