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 7,116,445, 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 | 7,116,445 | |
| -1 | -7,116,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,116,445.
Example:
1 x 7,116,445 = 7,116,445
and
-1 x -7,116,445 = 7,116,445
Notice both answers equal 7,116,445
With that explanation out of the way, let's continue. Next, we take the number 7,116,445 and divide it by 2:
7,116,445 ÷ 2 = 3,558,222.5
If the quotient is a whole number, then 2 and 3,558,222.5 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 | 7,116,445 | |
| -1 | -7,116,445 |
Now, we try dividing 7,116,445 by 3:
7,116,445 ÷ 3 = 2,372,148.3333
If the quotient is a whole number, then 3 and 2,372,148.3333 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 | 7,116,445 | |
| -1 | -7,116,445 |
Let's try dividing by 4:
7,116,445 ÷ 4 = 1,779,111.25
If the quotient is a whole number, then 4 and 1,779,111.25 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 | 7,116,445 | |
| -1 | 7,116,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 127 | 635 | 889 | 1,601 | 4,445 | 8,005 | 11,207 | 56,035 | 203,327 | 1,016,635 | 1,423,289 | 7,116,445 |
| -1 | -5 | -7 | -35 | -127 | -635 | -889 | -1,601 | -4,445 | -8,005 | -11,207 | -56,035 | -203,327 | -1,016,635 | -1,423,289 | -7,116,445 |
