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 713,607,503, 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 | 713,607,503 | |
| -1 | -713,607,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 713,607,503.
Example:
1 x 713,607,503 = 713,607,503
and
-1 x -713,607,503 = 713,607,503
Notice both answers equal 713,607,503
With that explanation out of the way, let's continue. Next, we take the number 713,607,503 and divide it by 2:
713,607,503 ÷ 2 = 356,803,751.5
If the quotient is a whole number, then 2 and 356,803,751.5 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 | 713,607,503 | |
| -1 | -713,607,503 |
Now, we try dividing 713,607,503 by 3:
713,607,503 ÷ 3 = 237,869,167.6667
If the quotient is a whole number, then 3 and 237,869,167.6667 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 | 713,607,503 | |
| -1 | -713,607,503 |
Let's try dividing by 4:
713,607,503 ÷ 4 = 178,401,875.75
If the quotient is a whole number, then 4 and 178,401,875.75 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 | 713,607,503 | |
| -1 | 713,607,503 |
If you did it right, you will end up with this table:
| 1 | 7 | 107 | 353 | 749 | 2,471 | 2,699 | 18,893 | 37,771 | 264,397 | 288,793 | 952,747 | 2,021,551 | 6,669,229 | 101,943,929 | 713,607,503 |
| -1 | -7 | -107 | -353 | -749 | -2,471 | -2,699 | -18,893 | -37,771 | -264,397 | -288,793 | -952,747 | -2,021,551 | -6,669,229 | -101,943,929 | -713,607,503 |
