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 7,174,105, 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 | 7,174,105 | |
| -1 | -7,174,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,174,105.
Example:
1 x 7,174,105 = 7,174,105
and
-1 x -7,174,105 = 7,174,105
Notice both answers equal 7,174,105
With that explanation out of the way, let's continue. Next, we take the number 7,174,105 and divide it by 2:
7,174,105 ÷ 2 = 3,587,052.5
If the quotient is a whole number, then 2 and 3,587,052.5 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 | 7,174,105 | |
| -1 | -7,174,105 |
Now, we try dividing 7,174,105 by 3:
7,174,105 ÷ 3 = 2,391,368.3333
If the quotient is a whole number, then 3 and 2,391,368.3333 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 | 7,174,105 | |
| -1 | -7,174,105 |
Let's try dividing by 4:
7,174,105 ÷ 4 = 1,793,526.25
If the quotient is a whole number, then 4 and 1,793,526.25 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 | 7,174,105 | |
| -1 | 7,174,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 83 | 293 | 295 | 415 | 1,465 | 4,897 | 17,287 | 24,319 | 24,485 | 86,435 | 121,595 | 1,434,821 | 7,174,105 |
| -1 | -5 | -59 | -83 | -293 | -295 | -415 | -1,465 | -4,897 | -17,287 | -24,319 | -24,485 | -86,435 | -121,595 | -1,434,821 | -7,174,105 |
