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 3,401,645, 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 | 3,401,645 | |
| -1 | -3,401,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,401,645.
Example:
1 x 3,401,645 = 3,401,645
and
-1 x -3,401,645 = 3,401,645
Notice both answers equal 3,401,645
With that explanation out of the way, let's continue. Next, we take the number 3,401,645 and divide it by 2:
3,401,645 ÷ 2 = 1,700,822.5
If the quotient is a whole number, then 2 and 1,700,822.5 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 | 3,401,645 | |
| -1 | -3,401,645 |
Now, we try dividing 3,401,645 by 3:
3,401,645 ÷ 3 = 1,133,881.6667
If the quotient is a whole number, then 3 and 1,133,881.6667 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 | 3,401,645 | |
| -1 | -3,401,645 |
Let's try dividing by 4:
3,401,645 ÷ 4 = 850,411.25
If the quotient is a whole number, then 4 and 850,411.25 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 | 3,401,645 | |
| -1 | 3,401,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 59 | 65 | 295 | 767 | 887 | 3,835 | 4,435 | 11,531 | 52,333 | 57,655 | 261,665 | 680,329 | 3,401,645 |
| -1 | -5 | -13 | -59 | -65 | -295 | -767 | -887 | -3,835 | -4,435 | -11,531 | -52,333 | -57,655 | -261,665 | -680,329 | -3,401,645 |
