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 3,816,085, 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 | 3,816,085 | |
| -1 | -3,816,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,816,085.
Example:
1 x 3,816,085 = 3,816,085
and
-1 x -3,816,085 = 3,816,085
Notice both answers equal 3,816,085
With that explanation out of the way, let's continue. Next, we take the number 3,816,085 and divide it by 2:
3,816,085 ÷ 2 = 1,908,042.5
If the quotient is a whole number, then 2 and 1,908,042.5 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 | 3,816,085 | |
| -1 | -3,816,085 |
Now, we try dividing 3,816,085 by 3:
3,816,085 ÷ 3 = 1,272,028.3333
If the quotient is a whole number, then 3 and 1,272,028.3333 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 | 3,816,085 | |
| -1 | -3,816,085 |
Let's try dividing by 4:
3,816,085 ÷ 4 = 954,021.25
If the quotient is a whole number, then 4 and 954,021.25 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 | 3,816,085 | |
| -1 | 3,816,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 8,387 | 41,935 | 58,709 | 109,031 | 293,545 | 545,155 | 763,217 | 3,816,085 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -8,387 | -41,935 | -58,709 | -109,031 | -293,545 | -545,155 | -763,217 | -3,816,085 |
