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 4,214,045, 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 | 4,214,045 | |
| -1 | -4,214,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,214,045.
Example:
1 x 4,214,045 = 4,214,045
and
-1 x -4,214,045 = 4,214,045
Notice both answers equal 4,214,045
With that explanation out of the way, let's continue. Next, we take the number 4,214,045 and divide it by 2:
4,214,045 ÷ 2 = 2,107,022.5
If the quotient is a whole number, then 2 and 2,107,022.5 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 | 4,214,045 | |
| -1 | -4,214,045 |
Now, we try dividing 4,214,045 by 3:
4,214,045 ÷ 3 = 1,404,681.6667
If the quotient is a whole number, then 3 and 1,404,681.6667 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 | 4,214,045 | |
| -1 | -4,214,045 |
Let's try dividing by 4:
4,214,045 ÷ 4 = 1,053,511.25
If the quotient is a whole number, then 4 and 1,053,511.25 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 | 4,214,045 | |
| -1 | 4,214,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 4,507 | 22,535 | 49,577 | 76,619 | 247,885 | 383,095 | 842,809 | 4,214,045 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -4,507 | -22,535 | -49,577 | -76,619 | -247,885 | -383,095 | -842,809 | -4,214,045 |
