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 3,554,215, 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 | 3,554,215 | |
| -1 | -3,554,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,554,215.
Example:
1 x 3,554,215 = 3,554,215
and
-1 x -3,554,215 = 3,554,215
Notice both answers equal 3,554,215
With that explanation out of the way, let's continue. Next, we take the number 3,554,215 and divide it by 2:
3,554,215 ÷ 2 = 1,777,107.5
If the quotient is a whole number, then 2 and 1,777,107.5 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 | 3,554,215 | |
| -1 | -3,554,215 |
Now, we try dividing 3,554,215 by 3:
3,554,215 ÷ 3 = 1,184,738.3333
If the quotient is a whole number, then 3 and 1,184,738.3333 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 | 3,554,215 | |
| -1 | -3,554,215 |
Let's try dividing by 4:
3,554,215 ÷ 4 = 888,553.75
If the quotient is a whole number, then 4 and 888,553.75 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 | 3,554,215 | |
| -1 | 3,554,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 89 | 163 | 245 | 445 | 623 | 815 | 1,141 | 3,115 | 4,361 | 5,705 | 7,987 | 14,507 | 21,805 | 39,935 | 72,535 | 101,549 | 507,745 | 710,843 | 3,554,215 |
| -1 | -5 | -7 | -35 | -49 | -89 | -163 | -245 | -445 | -623 | -815 | -1,141 | -3,115 | -4,361 | -5,705 | -7,987 | -14,507 | -21,805 | -39,935 | -72,535 | -101,549 | -507,745 | -710,843 | -3,554,215 |
