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 748,300,105, 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 | 748,300,105 | |
| -1 | -748,300,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 748,300,105.
Example:
1 x 748,300,105 = 748,300,105
and
-1 x -748,300,105 = 748,300,105
Notice both answers equal 748,300,105
With that explanation out of the way, let's continue. Next, we take the number 748,300,105 and divide it by 2:
748,300,105 ÷ 2 = 374,150,052.5
If the quotient is a whole number, then 2 and 374,150,052.5 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 | 748,300,105 | |
| -1 | -748,300,105 |
Now, we try dividing 748,300,105 by 3:
748,300,105 ÷ 3 = 249,433,368.3333
If the quotient is a whole number, then 3 and 249,433,368.3333 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 | 748,300,105 | |
| -1 | -748,300,105 |
Let's try dividing by 4:
748,300,105 ÷ 4 = 187,075,026.25
If the quotient is a whole number, then 4 and 187,075,026.25 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 | 748,300,105 | |
| -1 | 748,300,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 271 | 1,355 | 1,897 | 9,485 | 78,893 | 394,465 | 552,251 | 2,761,255 | 21,380,003 | 106,900,015 | 149,660,021 | 748,300,105 |
| -1 | -5 | -7 | -35 | -271 | -1,355 | -1,897 | -9,485 | -78,893 | -394,465 | -552,251 | -2,761,255 | -21,380,003 | -106,900,015 | -149,660,021 | -748,300,105 |
