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 4,270,343, 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 | 4,270,343 | |
| -1 | -4,270,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,270,343.
Example:
1 x 4,270,343 = 4,270,343
and
-1 x -4,270,343 = 4,270,343
Notice both answers equal 4,270,343
With that explanation out of the way, let's continue. Next, we take the number 4,270,343 and divide it by 2:
4,270,343 ÷ 2 = 2,135,171.5
If the quotient is a whole number, then 2 and 2,135,171.5 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 | 4,270,343 | |
| -1 | -4,270,343 |
Now, we try dividing 4,270,343 by 3:
4,270,343 ÷ 3 = 1,423,447.6667
If the quotient is a whole number, then 3 and 1,423,447.6667 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 | 4,270,343 | |
| -1 | -4,270,343 |
Let's try dividing by 4:
4,270,343 ÷ 4 = 1,067,585.75
If the quotient is a whole number, then 4 and 1,067,585.75 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 | 4,270,343 | |
| -1 | 4,270,343 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 217 | 341 | 1,789 | 2,387 | 12,523 | 19,679 | 55,459 | 137,753 | 388,213 | 610,049 | 4,270,343 |
| -1 | -7 | -11 | -31 | -77 | -217 | -341 | -1,789 | -2,387 | -12,523 | -19,679 | -55,459 | -137,753 | -388,213 | -610,049 | -4,270,343 |
