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 748,654,855, 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 | 748,654,855 | |
| -1 | -748,654,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 748,654,855.
Example:
1 x 748,654,855 = 748,654,855
and
-1 x -748,654,855 = 748,654,855
Notice both answers equal 748,654,855
With that explanation out of the way, let's continue. Next, we take the number 748,654,855 and divide it by 2:
748,654,855 ÷ 2 = 374,327,427.5
If the quotient is a whole number, then 2 and 374,327,427.5 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 | 748,654,855 | |
| -1 | -748,654,855 |
Now, we try dividing 748,654,855 by 3:
748,654,855 ÷ 3 = 249,551,618.3333
If the quotient is a whole number, then 3 and 249,551,618.3333 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 | 748,654,855 | |
| -1 | -748,654,855 |
Let's try dividing by 4:
748,654,855 ÷ 4 = 187,163,713.75
If the quotient is a whole number, then 4 and 187,163,713.75 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 | 748,654,855 | |
| -1 | 748,654,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 37 | 65 | 185 | 481 | 2,405 | 311,291 | 1,556,455 | 4,046,783 | 11,517,767 | 20,233,915 | 57,588,835 | 149,730,971 | 748,654,855 |
| -1 | -5 | -13 | -37 | -65 | -185 | -481 | -2,405 | -311,291 | -1,556,455 | -4,046,783 | -11,517,767 | -20,233,915 | -57,588,835 | -149,730,971 | -748,654,855 |
