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 3,258,745, 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 | 3,258,745 | |
| -1 | -3,258,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,258,745.
Example:
1 x 3,258,745 = 3,258,745
and
-1 x -3,258,745 = 3,258,745
Notice both answers equal 3,258,745
With that explanation out of the way, let's continue. Next, we take the number 3,258,745 and divide it by 2:
3,258,745 ÷ 2 = 1,629,372.5
If the quotient is a whole number, then 2 and 1,629,372.5 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 | 3,258,745 | |
| -1 | -3,258,745 |
Now, we try dividing 3,258,745 by 3:
3,258,745 ÷ 3 = 1,086,248.3333
If the quotient is a whole number, then 3 and 1,086,248.3333 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 | 3,258,745 | |
| -1 | -3,258,745 |
Let's try dividing by 4:
3,258,745 ÷ 4 = 814,686.25
If the quotient is a whole number, then 4 and 814,686.25 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 | 3,258,745 | |
| -1 | 3,258,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 49 | 235 | 245 | 283 | 329 | 1,415 | 1,645 | 1,981 | 2,303 | 9,905 | 11,515 | 13,301 | 13,867 | 66,505 | 69,335 | 93,107 | 465,535 | 651,749 | 3,258,745 |
| -1 | -5 | -7 | -35 | -47 | -49 | -235 | -245 | -283 | -329 | -1,415 | -1,645 | -1,981 | -2,303 | -9,905 | -11,515 | -13,301 | -13,867 | -66,505 | -69,335 | -93,107 | -465,535 | -651,749 | -3,258,745 |
