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 4,342,105, 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 | 4,342,105 | |
| -1 | -4,342,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,342,105.
Example:
1 x 4,342,105 = 4,342,105
and
-1 x -4,342,105 = 4,342,105
Notice both answers equal 4,342,105
With that explanation out of the way, let's continue. Next, we take the number 4,342,105 and divide it by 2:
4,342,105 ÷ 2 = 2,171,052.5
If the quotient is a whole number, then 2 and 2,171,052.5 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 | 4,342,105 | |
| -1 | -4,342,105 |
Now, we try dividing 4,342,105 by 3:
4,342,105 ÷ 3 = 1,447,368.3333
If the quotient is a whole number, then 3 and 1,447,368.3333 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 | 4,342,105 | |
| -1 | -4,342,105 |
Let's try dividing by 4:
4,342,105 ÷ 4 = 1,085,526.25
If the quotient is a whole number, then 4 and 1,085,526.25 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 | 4,342,105 | |
| -1 | 4,342,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 59 | 205 | 295 | 359 | 1,795 | 2,419 | 12,095 | 14,719 | 21,181 | 73,595 | 105,905 | 868,421 | 4,342,105 |
| -1 | -5 | -41 | -59 | -205 | -295 | -359 | -1,795 | -2,419 | -12,095 | -14,719 | -21,181 | -73,595 | -105,905 | -868,421 | -4,342,105 |
