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 3,251,195, 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 | 3,251,195 | |
| -1 | -3,251,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,251,195.
Example:
1 x 3,251,195 = 3,251,195
and
-1 x -3,251,195 = 3,251,195
Notice both answers equal 3,251,195
With that explanation out of the way, let's continue. Next, we take the number 3,251,195 and divide it by 2:
3,251,195 ÷ 2 = 1,625,597.5
If the quotient is a whole number, then 2 and 1,625,597.5 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 | 3,251,195 | |
| -1 | -3,251,195 |
Now, we try dividing 3,251,195 by 3:
3,251,195 ÷ 3 = 1,083,731.6667
If the quotient is a whole number, then 3 and 1,083,731.6667 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 | 3,251,195 | |
| -1 | -3,251,195 |
Let's try dividing by 4:
3,251,195 ÷ 4 = 812,798.75
If the quotient is a whole number, then 4 and 812,798.75 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 | 3,251,195 | |
| -1 | 3,251,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 103 | 107 | 295 | 515 | 535 | 6,077 | 6,313 | 11,021 | 30,385 | 31,565 | 55,105 | 650,239 | 3,251,195 |
| -1 | -5 | -59 | -103 | -107 | -295 | -515 | -535 | -6,077 | -6,313 | -11,021 | -30,385 | -31,565 | -55,105 | -650,239 | -3,251,195 |
