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 7,417,085, 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 | 7,417,085 | |
| -1 | -7,417,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,417,085.
Example:
1 x 7,417,085 = 7,417,085
and
-1 x -7,417,085 = 7,417,085
Notice both answers equal 7,417,085
With that explanation out of the way, let's continue. Next, we take the number 7,417,085 and divide it by 2:
7,417,085 ÷ 2 = 3,708,542.5
If the quotient is a whole number, then 2 and 3,708,542.5 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 | 7,417,085 | |
| -1 | -7,417,085 |
Now, we try dividing 7,417,085 by 3:
7,417,085 ÷ 3 = 2,472,361.6667
If the quotient is a whole number, then 3 and 2,472,361.6667 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 | 7,417,085 | |
| -1 | -7,417,085 |
Let's try dividing by 4:
7,417,085 ÷ 4 = 1,854,271.25
If the quotient is a whole number, then 4 and 1,854,271.25 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 | 7,417,085 | |
| -1 | 7,417,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 53 | 65 | 265 | 689 | 2,153 | 3,445 | 10,765 | 27,989 | 114,109 | 139,945 | 570,545 | 1,483,417 | 7,417,085 |
| -1 | -5 | -13 | -53 | -65 | -265 | -689 | -2,153 | -3,445 | -10,765 | -27,989 | -114,109 | -139,945 | -570,545 | -1,483,417 | -7,417,085 |
