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 3,058,891, 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 | 3,058,891 | |
| -1 | -3,058,891 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,058,891.
Example:
1 x 3,058,891 = 3,058,891
and
-1 x -3,058,891 = 3,058,891
Notice both answers equal 3,058,891
With that explanation out of the way, let's continue. Next, we take the number 3,058,891 and divide it by 2:
3,058,891 ÷ 2 = 1,529,445.5
If the quotient is a whole number, then 2 and 1,529,445.5 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 | 3,058,891 | |
| -1 | -3,058,891 |
Now, we try dividing 3,058,891 by 3:
3,058,891 ÷ 3 = 1,019,630.3333
If the quotient is a whole number, then 3 and 1,019,630.3333 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 | 3,058,891 | |
| -1 | -3,058,891 |
Let's try dividing by 4:
3,058,891 ÷ 4 = 764,722.75
If the quotient is a whole number, then 4 and 764,722.75 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 | 3,058,891 | |
| -1 | 3,058,891 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 43 | 223 | 319 | 473 | 1,247 | 2,453 | 6,467 | 9,589 | 13,717 | 71,137 | 105,479 | 278,081 | 3,058,891 |
| -1 | -11 | -29 | -43 | -223 | -319 | -473 | -1,247 | -2,453 | -6,467 | -9,589 | -13,717 | -71,137 | -105,479 | -278,081 | -3,058,891 |
