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 703,700,431, 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 | 703,700,431 | |
| -1 | -703,700,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 703,700,431.
Example:
1 x 703,700,431 = 703,700,431
and
-1 x -703,700,431 = 703,700,431
Notice both answers equal 703,700,431
With that explanation out of the way, let's continue. Next, we take the number 703,700,431 and divide it by 2:
703,700,431 ÷ 2 = 351,850,215.5
If the quotient is a whole number, then 2 and 351,850,215.5 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 | 703,700,431 | |
| -1 | -703,700,431 |
Now, we try dividing 703,700,431 by 3:
703,700,431 ÷ 3 = 234,566,810.3333
If the quotient is a whole number, then 3 and 234,566,810.3333 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 | 703,700,431 | |
| -1 | -703,700,431 |
Let's try dividing by 4:
703,700,431 ÷ 4 = 175,925,107.75
If the quotient is a whole number, then 4 and 175,925,107.75 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 | 703,700,431 | |
| -1 | 703,700,431 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 101 | 119 | 707 | 1,717 | 12,019 | 58,549 | 409,843 | 995,333 | 5,913,449 | 6,967,331 | 41,394,143 | 100,528,633 | 703,700,431 |
| -1 | -7 | -17 | -101 | -119 | -707 | -1,717 | -12,019 | -58,549 | -409,843 | -995,333 | -5,913,449 | -6,967,331 | -41,394,143 | -100,528,633 | -703,700,431 |
