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 712,114,543, 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 | 712,114,543 | |
| -1 | -712,114,543 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 712,114,543.
Example:
1 x 712,114,543 = 712,114,543
and
-1 x -712,114,543 = 712,114,543
Notice both answers equal 712,114,543
With that explanation out of the way, let's continue. Next, we take the number 712,114,543 and divide it by 2:
712,114,543 ÷ 2 = 356,057,271.5
If the quotient is a whole number, then 2 and 356,057,271.5 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 | 712,114,543 | |
| -1 | -712,114,543 |
Now, we try dividing 712,114,543 by 3:
712,114,543 ÷ 3 = 237,371,514.3333
If the quotient is a whole number, then 3 and 237,371,514.3333 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 | 712,114,543 | |
| -1 | -712,114,543 |
Let's try dividing by 4:
712,114,543 ÷ 4 = 178,028,635.75
If the quotient is a whole number, then 4 and 178,028,635.75 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 | 712,114,543 | |
| -1 | 712,114,543 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 89 | 259 | 623 | 3,293 | 23,051 | 30,893 | 216,251 | 1,143,041 | 2,749,477 | 8,001,287 | 19,246,339 | 101,730,649 | 712,114,543 |
| -1 | -7 | -37 | -89 | -259 | -623 | -3,293 | -23,051 | -30,893 | -216,251 | -1,143,041 | -2,749,477 | -8,001,287 | -19,246,339 | -101,730,649 | -712,114,543 |
