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 3,904,549, 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 | 3,904,549 | |
| -1 | -3,904,549 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,904,549.
Example:
1 x 3,904,549 = 3,904,549
and
-1 x -3,904,549 = 3,904,549
Notice both answers equal 3,904,549
With that explanation out of the way, let's continue. Next, we take the number 3,904,549 and divide it by 2:
3,904,549 ÷ 2 = 1,952,274.5
If the quotient is a whole number, then 2 and 1,952,274.5 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 | 3,904,549 | |
| -1 | -3,904,549 |
Now, we try dividing 3,904,549 by 3:
3,904,549 ÷ 3 = 1,301,516.3333
If the quotient is a whole number, then 3 and 1,301,516.3333 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 | 3,904,549 | |
| -1 | -3,904,549 |
Let's try dividing by 4:
3,904,549 ÷ 4 = 976,137.25
If the quotient is a whole number, then 4 and 976,137.25 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 | 3,904,549 | |
| -1 | 3,904,549 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 61 | 121 | 253 | 529 | 671 | 1,403 | 2,783 | 5,819 | 7,381 | 15,433 | 32,269 | 64,009 | 169,763 | 354,959 | 3,904,549 |
| -1 | -11 | -23 | -61 | -121 | -253 | -529 | -671 | -1,403 | -2,783 | -5,819 | -7,381 | -15,433 | -32,269 | -64,009 | -169,763 | -354,959 | -3,904,549 |
