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 7,048,235, 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 | 7,048,235 | |
| -1 | -7,048,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,048,235.
Example:
1 x 7,048,235 = 7,048,235
and
-1 x -7,048,235 = 7,048,235
Notice both answers equal 7,048,235
With that explanation out of the way, let's continue. Next, we take the number 7,048,235 and divide it by 2:
7,048,235 ÷ 2 = 3,524,117.5
If the quotient is a whole number, then 2 and 3,524,117.5 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 | 7,048,235 | |
| -1 | -7,048,235 |
Now, we try dividing 7,048,235 by 3:
7,048,235 ÷ 3 = 2,349,411.6667
If the quotient is a whole number, then 3 and 2,349,411.6667 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 | 7,048,235 | |
| -1 | -7,048,235 |
Let's try dividing by 4:
7,048,235 ÷ 4 = 1,762,058.75
If the quotient is a whole number, then 4 and 1,762,058.75 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 | 7,048,235 | |
| -1 | 7,048,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 167 | 367 | 835 | 1,835 | 3,841 | 8,441 | 19,205 | 42,205 | 61,289 | 306,445 | 1,409,647 | 7,048,235 |
| -1 | -5 | -23 | -115 | -167 | -367 | -835 | -1,835 | -3,841 | -8,441 | -19,205 | -42,205 | -61,289 | -306,445 | -1,409,647 | -7,048,235 |
