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 2,406,065, 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 | 2,406,065 | |
| -1 | -2,406,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,406,065.
Example:
1 x 2,406,065 = 2,406,065
and
-1 x -2,406,065 = 2,406,065
Notice both answers equal 2,406,065
With that explanation out of the way, let's continue. Next, we take the number 2,406,065 and divide it by 2:
2,406,065 ÷ 2 = 1,203,032.5
If the quotient is a whole number, then 2 and 1,203,032.5 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 | 2,406,065 | |
| -1 | -2,406,065 |
Now, we try dividing 2,406,065 by 3:
2,406,065 ÷ 3 = 802,021.6667
If the quotient is a whole number, then 3 and 802,021.6667 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 | 2,406,065 | |
| -1 | -2,406,065 |
Let's try dividing by 4:
2,406,065 ÷ 4 = 601,516.25
If the quotient is a whole number, then 4 and 601,516.25 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 | 2,406,065 | |
| -1 | 2,406,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 31 | 43 | 95 | 155 | 215 | 361 | 589 | 817 | 1,333 | 1,805 | 2,945 | 4,085 | 6,665 | 11,191 | 15,523 | 25,327 | 55,955 | 77,615 | 126,635 | 481,213 | 2,406,065 |
| -1 | -5 | -19 | -31 | -43 | -95 | -155 | -215 | -361 | -589 | -817 | -1,333 | -1,805 | -2,945 | -4,085 | -6,665 | -11,191 | -15,523 | -25,327 | -55,955 | -77,615 | -126,635 | -481,213 | -2,406,065 |
