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 4,000,843, 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 | 4,000,843 | |
| -1 | -4,000,843 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,000,843.
Example:
1 x 4,000,843 = 4,000,843
and
-1 x -4,000,843 = 4,000,843
Notice both answers equal 4,000,843
With that explanation out of the way, let's continue. Next, we take the number 4,000,843 and divide it by 2:
4,000,843 ÷ 2 = 2,000,421.5
If the quotient is a whole number, then 2 and 2,000,421.5 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 | 4,000,843 | |
| -1 | -4,000,843 |
Now, we try dividing 4,000,843 by 3:
4,000,843 ÷ 3 = 1,333,614.3333
If the quotient is a whole number, then 3 and 1,333,614.3333 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 | 4,000,843 | |
| -1 | -4,000,843 |
Let's try dividing by 4:
4,000,843 ÷ 4 = 1,000,210.75
If the quotient is a whole number, then 4 and 1,000,210.75 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 | 4,000,843 | |
| -1 | 4,000,843 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 223 | 233 | 1,561 | 1,631 | 2,453 | 2,563 | 17,171 | 17,941 | 51,959 | 363,713 | 571,549 | 4,000,843 |
| -1 | -7 | -11 | -77 | -223 | -233 | -1,561 | -1,631 | -2,453 | -2,563 | -17,171 | -17,941 | -51,959 | -363,713 | -571,549 | -4,000,843 |
