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 8,143,235, 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 | 8,143,235 | |
| -1 | -8,143,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,143,235.
Example:
1 x 8,143,235 = 8,143,235
and
-1 x -8,143,235 = 8,143,235
Notice both answers equal 8,143,235
With that explanation out of the way, let's continue. Next, we take the number 8,143,235 and divide it by 2:
8,143,235 ÷ 2 = 4,071,617.5
If the quotient is a whole number, then 2 and 4,071,617.5 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 | 8,143,235 | |
| -1 | -8,143,235 |
Now, we try dividing 8,143,235 by 3:
8,143,235 ÷ 3 = 2,714,411.6667
If the quotient is a whole number, then 3 and 2,714,411.6667 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 | 8,143,235 | |
| -1 | -8,143,235 |
Let's try dividing by 4:
8,143,235 ÷ 4 = 2,035,808.75
If the quotient is a whole number, then 4 and 2,035,808.75 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 | 8,143,235 | |
| -1 | 8,143,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 107 | 155 | 491 | 535 | 2,455 | 3,317 | 15,221 | 16,585 | 52,537 | 76,105 | 262,685 | 1,628,647 | 8,143,235 |
| -1 | -5 | -31 | -107 | -155 | -491 | -535 | -2,455 | -3,317 | -15,221 | -16,585 | -52,537 | -76,105 | -262,685 | -1,628,647 | -8,143,235 |
