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 3,398,815, 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 | 3,398,815 | |
| -1 | -3,398,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,398,815.
Example:
1 x 3,398,815 = 3,398,815
and
-1 x -3,398,815 = 3,398,815
Notice both answers equal 3,398,815
With that explanation out of the way, let's continue. Next, we take the number 3,398,815 and divide it by 2:
3,398,815 ÷ 2 = 1,699,407.5
If the quotient is a whole number, then 2 and 1,699,407.5 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 | 3,398,815 | |
| -1 | -3,398,815 |
Now, we try dividing 3,398,815 by 3:
3,398,815 ÷ 3 = 1,132,938.3333
If the quotient is a whole number, then 3 and 1,132,938.3333 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 | 3,398,815 | |
| -1 | -3,398,815 |
Let's try dividing by 4:
3,398,815 ÷ 4 = 849,703.75
If the quotient is a whole number, then 4 and 849,703.75 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 | 3,398,815 | |
| -1 | 3,398,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 269 | 361 | 665 | 1,345 | 1,805 | 1,883 | 2,527 | 5,111 | 9,415 | 12,635 | 25,555 | 35,777 | 97,109 | 178,885 | 485,545 | 679,763 | 3,398,815 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -269 | -361 | -665 | -1,345 | -1,805 | -1,883 | -2,527 | -5,111 | -9,415 | -12,635 | -25,555 | -35,777 | -97,109 | -178,885 | -485,545 | -679,763 | -3,398,815 |
