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 2,848,945, 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 | 2,848,945 | |
| -1 | -2,848,945 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,848,945.
Example:
1 x 2,848,945 = 2,848,945
and
-1 x -2,848,945 = 2,848,945
Notice both answers equal 2,848,945
With that explanation out of the way, let's continue. Next, we take the number 2,848,945 and divide it by 2:
2,848,945 ÷ 2 = 1,424,472.5
If the quotient is a whole number, then 2 and 1,424,472.5 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 | 2,848,945 | |
| -1 | -2,848,945 |
Now, we try dividing 2,848,945 by 3:
2,848,945 ÷ 3 = 949,648.3333
If the quotient is a whole number, then 3 and 949,648.3333 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 | 2,848,945 | |
| -1 | -2,848,945 |
Let's try dividing by 4:
2,848,945 ÷ 4 = 712,236.25
If the quotient is a whole number, then 4 and 712,236.25 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 | 2,848,945 | |
| -1 | 2,848,945 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 121 | 187 | 277 | 605 | 935 | 1,385 | 2,057 | 3,047 | 4,709 | 10,285 | 15,235 | 23,545 | 33,517 | 51,799 | 167,585 | 258,995 | 569,789 | 2,848,945 |
| -1 | -5 | -11 | -17 | -55 | -85 | -121 | -187 | -277 | -605 | -935 | -1,385 | -2,057 | -3,047 | -4,709 | -10,285 | -15,235 | -23,545 | -33,517 | -51,799 | -167,585 | -258,995 | -569,789 | -2,848,945 |
