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 712,740,103, 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 | 712,740,103 | |
| -1 | -712,740,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 712,740,103.
Example:
1 x 712,740,103 = 712,740,103
and
-1 x -712,740,103 = 712,740,103
Notice both answers equal 712,740,103
With that explanation out of the way, let's continue. Next, we take the number 712,740,103 and divide it by 2:
712,740,103 ÷ 2 = 356,370,051.5
If the quotient is a whole number, then 2 and 356,370,051.5 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 | 712,740,103 | |
| -1 | -712,740,103 |
Now, we try dividing 712,740,103 by 3:
712,740,103 ÷ 3 = 237,580,034.3333
If the quotient is a whole number, then 3 and 237,580,034.3333 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 | 712,740,103 | |
| -1 | -712,740,103 |
Let's try dividing by 4:
712,740,103 ÷ 4 = 178,185,025.75
If the quotient is a whole number, then 4 and 178,185,025.75 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 | 712,740,103 | |
| -1 | 712,740,103 |
If you did it right, you will end up with this table:
| 1 | 19 | 71 | 307 | 1,349 | 1,721 | 5,833 | 21,797 | 32,699 | 122,191 | 414,143 | 528,347 | 2,321,629 | 10,038,593 | 37,512,637 | 712,740,103 |
| -1 | -19 | -71 | -307 | -1,349 | -1,721 | -5,833 | -21,797 | -32,699 | -122,191 | -414,143 | -528,347 | -2,321,629 | -10,038,593 | -37,512,637 | -712,740,103 |
