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 7,116,629, 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 | 7,116,629 | |
| -1 | -7,116,629 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,116,629.
Example:
1 x 7,116,629 = 7,116,629
and
-1 x -7,116,629 = 7,116,629
Notice both answers equal 7,116,629
With that explanation out of the way, let's continue. Next, we take the number 7,116,629 and divide it by 2:
7,116,629 ÷ 2 = 3,558,314.5
If the quotient is a whole number, then 2 and 3,558,314.5 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 | 7,116,629 | |
| -1 | -7,116,629 |
Now, we try dividing 7,116,629 by 3:
7,116,629 ÷ 3 = 2,372,209.6667
If the quotient is a whole number, then 3 and 2,372,209.6667 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 | 7,116,629 | |
| -1 | -7,116,629 |
Let's try dividing by 4:
7,116,629 ÷ 4 = 1,779,157.25
If the quotient is a whole number, then 4 and 1,779,157.25 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 | 7,116,629 | |
| -1 | 7,116,629 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 43 | 377 | 439 | 559 | 1,247 | 5,707 | 12,731 | 16,211 | 18,877 | 165,503 | 245,401 | 547,433 | 7,116,629 |
| -1 | -13 | -29 | -43 | -377 | -439 | -559 | -1,247 | -5,707 | -12,731 | -16,211 | -18,877 | -165,503 | -245,401 | -547,433 | -7,116,629 |
