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 2,846,515, 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 | 2,846,515 | |
| -1 | -2,846,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,846,515.
Example:
1 x 2,846,515 = 2,846,515
and
-1 x -2,846,515 = 2,846,515
Notice both answers equal 2,846,515
With that explanation out of the way, let's continue. Next, we take the number 2,846,515 and divide it by 2:
2,846,515 ÷ 2 = 1,423,257.5
If the quotient is a whole number, then 2 and 1,423,257.5 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 | 2,846,515 | |
| -1 | -2,846,515 |
Now, we try dividing 2,846,515 by 3:
2,846,515 ÷ 3 = 948,838.3333
If the quotient is a whole number, then 3 and 948,838.3333 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 | 2,846,515 | |
| -1 | -2,846,515 |
Let's try dividing by 4:
2,846,515 ÷ 4 = 711,628.75
If the quotient is a whole number, then 4 and 711,628.75 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 | 2,846,515 | |
| -1 | 2,846,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 167 | 487 | 835 | 1,169 | 2,435 | 3,409 | 5,845 | 17,045 | 81,329 | 406,645 | 569,303 | 2,846,515 |
| -1 | -5 | -7 | -35 | -167 | -487 | -835 | -1,169 | -2,435 | -3,409 | -5,845 | -17,045 | -81,329 | -406,645 | -569,303 | -2,846,515 |
