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 3,518,905, 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 | 3,518,905 | |
| -1 | -3,518,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,518,905.
Example:
1 x 3,518,905 = 3,518,905
and
-1 x -3,518,905 = 3,518,905
Notice both answers equal 3,518,905
With that explanation out of the way, let's continue. Next, we take the number 3,518,905 and divide it by 2:
3,518,905 ÷ 2 = 1,759,452.5
If the quotient is a whole number, then 2 and 1,759,452.5 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 | 3,518,905 | |
| -1 | -3,518,905 |
Now, we try dividing 3,518,905 by 3:
3,518,905 ÷ 3 = 1,172,968.3333
If the quotient is a whole number, then 3 and 1,172,968.3333 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 | 3,518,905 | |
| -1 | -3,518,905 |
Let's try dividing by 4:
3,518,905 ÷ 4 = 879,726.25
If the quotient is a whole number, then 4 and 879,726.25 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 | 3,518,905 | |
| -1 | 3,518,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 43 | 65 | 215 | 559 | 1,259 | 2,795 | 6,295 | 16,367 | 54,137 | 81,835 | 270,685 | 703,781 | 3,518,905 |
| -1 | -5 | -13 | -43 | -65 | -215 | -559 | -1,259 | -2,795 | -6,295 | -16,367 | -54,137 | -81,835 | -270,685 | -703,781 | -3,518,905 |
