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 745,246,255, 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 | 745,246,255 | |
| -1 | -745,246,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 745,246,255.
Example:
1 x 745,246,255 = 745,246,255
and
-1 x -745,246,255 = 745,246,255
Notice both answers equal 745,246,255
With that explanation out of the way, let's continue. Next, we take the number 745,246,255 and divide it by 2:
745,246,255 ÷ 2 = 372,623,127.5
If the quotient is a whole number, then 2 and 372,623,127.5 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 | 745,246,255 | |
| -1 | -745,246,255 |
Now, we try dividing 745,246,255 by 3:
745,246,255 ÷ 3 = 248,415,418.3333
If the quotient is a whole number, then 3 and 248,415,418.3333 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 | 745,246,255 | |
| -1 | -745,246,255 |
Let's try dividing by 4:
745,246,255 ÷ 4 = 186,311,563.75
If the quotient is a whole number, then 4 and 186,311,563.75 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 | 745,246,255 | |
| -1 | 745,246,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 674,431 | 3,372,155 | 8,767,603 | 11,465,327 | 43,838,015 | 57,326,635 | 149,049,251 | 745,246,255 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -674,431 | -3,372,155 | -8,767,603 | -11,465,327 | -43,838,015 | -57,326,635 | -149,049,251 | -745,246,255 |
