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 3,578,135, 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 | 3,578,135 | |
| -1 | -3,578,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,578,135.
Example:
1 x 3,578,135 = 3,578,135
and
-1 x -3,578,135 = 3,578,135
Notice both answers equal 3,578,135
With that explanation out of the way, let's continue. Next, we take the number 3,578,135 and divide it by 2:
3,578,135 ÷ 2 = 1,789,067.5
If the quotient is a whole number, then 2 and 1,789,067.5 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 | 3,578,135 | |
| -1 | -3,578,135 |
Now, we try dividing 3,578,135 by 3:
3,578,135 ÷ 3 = 1,192,711.6667
If the quotient is a whole number, then 3 and 1,192,711.6667 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 | 3,578,135 | |
| -1 | -3,578,135 |
Let's try dividing by 4:
3,578,135 ÷ 4 = 894,533.75
If the quotient is a whole number, then 4 and 894,533.75 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 | 3,578,135 | |
| -1 | 3,578,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 67 | 335 | 737 | 971 | 3,685 | 4,855 | 10,681 | 53,405 | 65,057 | 325,285 | 715,627 | 3,578,135 |
| -1 | -5 | -11 | -55 | -67 | -335 | -737 | -971 | -3,685 | -4,855 | -10,681 | -53,405 | -65,057 | -325,285 | -715,627 | -3,578,135 |
