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 7,017,277, 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 | 7,017,277 | |
| -1 | -7,017,277 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,017,277.
Example:
1 x 7,017,277 = 7,017,277
and
-1 x -7,017,277 = 7,017,277
Notice both answers equal 7,017,277
With that explanation out of the way, let's continue. Next, we take the number 7,017,277 and divide it by 2:
7,017,277 ÷ 2 = 3,508,638.5
If the quotient is a whole number, then 2 and 3,508,638.5 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 | 7,017,277 | |
| -1 | -7,017,277 |
Now, we try dividing 7,017,277 by 3:
7,017,277 ÷ 3 = 2,339,092.3333
If the quotient is a whole number, then 3 and 2,339,092.3333 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 | 7,017,277 | |
| -1 | -7,017,277 |
Let's try dividing by 4:
7,017,277 ÷ 4 = 1,754,319.25
If the quotient is a whole number, then 4 and 1,754,319.25 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 | 7,017,277 | |
| -1 | 7,017,277 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 131 | 137 | 391 | 2,227 | 2,329 | 3,013 | 3,151 | 17,947 | 51,221 | 53,567 | 305,099 | 412,781 | 7,017,277 |
| -1 | -17 | -23 | -131 | -137 | -391 | -2,227 | -2,329 | -3,013 | -3,151 | -17,947 | -51,221 | -53,567 | -305,099 | -412,781 | -7,017,277 |
