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 3,051,235, 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 | 3,051,235 | |
| -1 | -3,051,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,051,235.
Example:
1 x 3,051,235 = 3,051,235
and
-1 x -3,051,235 = 3,051,235
Notice both answers equal 3,051,235
With that explanation out of the way, let's continue. Next, we take the number 3,051,235 and divide it by 2:
3,051,235 ÷ 2 = 1,525,617.5
If the quotient is a whole number, then 2 and 1,525,617.5 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 | 3,051,235 | |
| -1 | -3,051,235 |
Now, we try dividing 3,051,235 by 3:
3,051,235 ÷ 3 = 1,017,078.3333
If the quotient is a whole number, then 3 and 1,017,078.3333 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 | 3,051,235 | |
| -1 | -3,051,235 |
Let's try dividing by 4:
3,051,235 ÷ 4 = 762,808.75
If the quotient is a whole number, then 4 and 762,808.75 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 | 3,051,235 | |
| -1 | 3,051,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 1,913 | 9,565 | 21,043 | 55,477 | 105,215 | 277,385 | 610,247 | 3,051,235 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -1,913 | -9,565 | -21,043 | -55,477 | -105,215 | -277,385 | -610,247 | -3,051,235 |
