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 3,389,045, 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 | 3,389,045 | |
| -1 | -3,389,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,389,045.
Example:
1 x 3,389,045 = 3,389,045
and
-1 x -3,389,045 = 3,389,045
Notice both answers equal 3,389,045
With that explanation out of the way, let's continue. Next, we take the number 3,389,045 and divide it by 2:
3,389,045 ÷ 2 = 1,694,522.5
If the quotient is a whole number, then 2 and 1,694,522.5 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 | 3,389,045 | |
| -1 | -3,389,045 |
Now, we try dividing 3,389,045 by 3:
3,389,045 ÷ 3 = 1,129,681.6667
If the quotient is a whole number, then 3 and 1,129,681.6667 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 | 3,389,045 | |
| -1 | -3,389,045 |
Let's try dividing by 4:
3,389,045 ÷ 4 = 847,261.25
If the quotient is a whole number, then 4 and 847,261.25 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 | 3,389,045 | |
| -1 | 3,389,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 43 | 55 | 215 | 473 | 1,433 | 2,365 | 7,165 | 15,763 | 61,619 | 78,815 | 308,095 | 677,809 | 3,389,045 |
| -1 | -5 | -11 | -43 | -55 | -215 | -473 | -1,433 | -2,365 | -7,165 | -15,763 | -61,619 | -78,815 | -308,095 | -677,809 | -3,389,045 |
