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 7,203,715, 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 | 7,203,715 | |
| -1 | -7,203,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,203,715.
Example:
1 x 7,203,715 = 7,203,715
and
-1 x -7,203,715 = 7,203,715
Notice both answers equal 7,203,715
With that explanation out of the way, let's continue. Next, we take the number 7,203,715 and divide it by 2:
7,203,715 ÷ 2 = 3,601,857.5
If the quotient is a whole number, then 2 and 3,601,857.5 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 | 7,203,715 | |
| -1 | -7,203,715 |
Now, we try dividing 7,203,715 by 3:
7,203,715 ÷ 3 = 2,401,238.3333
If the quotient is a whole number, then 3 and 2,401,238.3333 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 | 7,203,715 | |
| -1 | -7,203,715 |
Let's try dividing by 4:
7,203,715 ÷ 4 = 1,800,928.75
If the quotient is a whole number, then 4 and 1,800,928.75 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 | 7,203,715 | |
| -1 | 7,203,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 37 | 115 | 185 | 851 | 1,693 | 4,255 | 8,465 | 38,939 | 62,641 | 194,695 | 313,205 | 1,440,743 | 7,203,715 |
| -1 | -5 | -23 | -37 | -115 | -185 | -851 | -1,693 | -4,255 | -8,465 | -38,939 | -62,641 | -194,695 | -313,205 | -1,440,743 | -7,203,715 |
