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 3,554,243, 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 | 3,554,243 | |
| -1 | -3,554,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,554,243.
Example:
1 x 3,554,243 = 3,554,243
and
-1 x -3,554,243 = 3,554,243
Notice both answers equal 3,554,243
With that explanation out of the way, let's continue. Next, we take the number 3,554,243 and divide it by 2:
3,554,243 ÷ 2 = 1,777,121.5
If the quotient is a whole number, then 2 and 1,777,121.5 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 | 3,554,243 | |
| -1 | -3,554,243 |
Now, we try dividing 3,554,243 by 3:
3,554,243 ÷ 3 = 1,184,747.6667
If the quotient is a whole number, then 3 and 1,184,747.6667 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 | 3,554,243 | |
| -1 | -3,554,243 |
Let's try dividing by 4:
3,554,243 ÷ 4 = 888,560.75
If the quotient is a whole number, then 4 and 888,560.75 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 | 3,554,243 | |
| -1 | 3,554,243 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 217 | 341 | 1,489 | 2,387 | 10,423 | 16,379 | 46,159 | 114,653 | 323,113 | 507,749 | 3,554,243 |
| -1 | -7 | -11 | -31 | -77 | -217 | -341 | -1,489 | -2,387 | -10,423 | -16,379 | -46,159 | -114,653 | -323,113 | -507,749 | -3,554,243 |
