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 2,843,131, 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 | 2,843,131 | |
| -1 | -2,843,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,843,131.
Example:
1 x 2,843,131 = 2,843,131
and
-1 x -2,843,131 = 2,843,131
Notice both answers equal 2,843,131
With that explanation out of the way, let's continue. Next, we take the number 2,843,131 and divide it by 2:
2,843,131 ÷ 2 = 1,421,565.5
If the quotient is a whole number, then 2 and 1,421,565.5 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 | 2,843,131 | |
| -1 | -2,843,131 |
Now, we try dividing 2,843,131 by 3:
2,843,131 ÷ 3 = 947,710.3333
If the quotient is a whole number, then 3 and 947,710.3333 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 | 2,843,131 | |
| -1 | -2,843,131 |
Let's try dividing by 4:
2,843,131 ÷ 4 = 710,782.75
If the quotient is a whole number, then 4 and 710,782.75 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 | 2,843,131 | |
| -1 | 2,843,131 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 73 | 79 | 493 | 1,241 | 1,343 | 2,117 | 2,291 | 5,767 | 35,989 | 38,947 | 98,039 | 167,243 | 2,843,131 |
| -1 | -17 | -29 | -73 | -79 | -493 | -1,241 | -1,343 | -2,117 | -2,291 | -5,767 | -35,989 | -38,947 | -98,039 | -167,243 | -2,843,131 |
