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 703,423,015, 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 | 703,423,015 | |
| -1 | -703,423,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 703,423,015.
Example:
1 x 703,423,015 = 703,423,015
and
-1 x -703,423,015 = 703,423,015
Notice both answers equal 703,423,015
With that explanation out of the way, let's continue. Next, we take the number 703,423,015 and divide it by 2:
703,423,015 ÷ 2 = 351,711,507.5
If the quotient is a whole number, then 2 and 351,711,507.5 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 | 703,423,015 | |
| -1 | -703,423,015 |
Now, we try dividing 703,423,015 by 3:
703,423,015 ÷ 3 = 234,474,338.3333
If the quotient is a whole number, then 3 and 234,474,338.3333 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 | 703,423,015 | |
| -1 | -703,423,015 |
Let's try dividing by 4:
703,423,015 ÷ 4 = 175,855,753.75
If the quotient is a whole number, then 4 and 175,855,753.75 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 | 703,423,015 | |
| -1 | 703,423,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 181 | 905 | 5,611 | 25,073 | 28,055 | 125,365 | 777,263 | 3,886,315 | 4,538,213 | 22,691,065 | 140,684,603 | 703,423,015 |
| -1 | -5 | -31 | -155 | -181 | -905 | -5,611 | -25,073 | -28,055 | -125,365 | -777,263 | -3,886,315 | -4,538,213 | -22,691,065 | -140,684,603 | -703,423,015 |
