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 3,913,063, 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 | 3,913,063 | |
| -1 | -3,913,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,913,063.
Example:
1 x 3,913,063 = 3,913,063
and
-1 x -3,913,063 = 3,913,063
Notice both answers equal 3,913,063
With that explanation out of the way, let's continue. Next, we take the number 3,913,063 and divide it by 2:
3,913,063 ÷ 2 = 1,956,531.5
If the quotient is a whole number, then 2 and 1,956,531.5 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 | 3,913,063 | |
| -1 | -3,913,063 |
Now, we try dividing 3,913,063 by 3:
3,913,063 ÷ 3 = 1,304,354.3333
If the quotient is a whole number, then 3 and 1,304,354.3333 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 | 3,913,063 | |
| -1 | -3,913,063 |
Let's try dividing by 4:
3,913,063 ÷ 4 = 978,265.75
If the quotient is a whole number, then 4 and 978,265.75 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 | 3,913,063 | |
| -1 | 3,913,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 89 | 571 | 623 | 979 | 3,997 | 6,281 | 6,853 | 43,967 | 50,819 | 355,733 | 559,009 | 3,913,063 |
| -1 | -7 | -11 | -77 | -89 | -571 | -623 | -979 | -3,997 | -6,281 | -6,853 | -43,967 | -50,819 | -355,733 | -559,009 | -3,913,063 |
