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 7,003,115, 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 | 7,003,115 | |
| -1 | -7,003,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,003,115.
Example:
1 x 7,003,115 = 7,003,115
and
-1 x -7,003,115 = 7,003,115
Notice both answers equal 7,003,115
With that explanation out of the way, let's continue. Next, we take the number 7,003,115 and divide it by 2:
7,003,115 ÷ 2 = 3,501,557.5
If the quotient is a whole number, then 2 and 3,501,557.5 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 | 7,003,115 | |
| -1 | -7,003,115 |
Now, we try dividing 7,003,115 by 3:
7,003,115 ÷ 3 = 2,334,371.6667
If the quotient is a whole number, then 3 and 2,334,371.6667 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 | 7,003,115 | |
| -1 | -7,003,115 |
Let's try dividing by 4:
7,003,115 ÷ 4 = 1,750,778.75
If the quotient is a whole number, then 4 and 1,750,778.75 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 | 7,003,115 | |
| -1 | 7,003,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 10,531 | 52,655 | 73,717 | 200,089 | 368,585 | 1,000,445 | 1,400,623 | 7,003,115 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -10,531 | -52,655 | -73,717 | -200,089 | -368,585 | -1,000,445 | -1,400,623 | -7,003,115 |
