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 768,955, 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 | 768,955 | |
| -1 | -768,955 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 768,955.
Example:
1 x 768,955 = 768,955
and
-1 x -768,955 = 768,955
Notice both answers equal 768,955
With that explanation out of the way, let's continue. Next, we take the number 768,955 and divide it by 2:
768,955 ÷ 2 = 384,477.5
If the quotient is a whole number, then 2 and 384,477.5 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 | 768,955 | |
| -1 | -768,955 |
Now, we try dividing 768,955 by 3:
768,955 ÷ 3 = 256,318.3333
If the quotient is a whole number, then 3 and 256,318.3333 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 | 768,955 | |
| -1 | -768,955 |
Let's try dividing by 4:
768,955 ÷ 4 = 192,238.75
If the quotient is a whole number, then 4 and 192,238.75 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 | 768,955 | |
| -1 | 768,955 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 41 | 55 | 121 | 155 | 205 | 341 | 451 | 605 | 1,271 | 1,705 | 2,255 | 3,751 | 4,961 | 6,355 | 13,981 | 18,755 | 24,805 | 69,905 | 153,791 | 768,955 |
| -1 | -5 | -11 | -31 | -41 | -55 | -121 | -155 | -205 | -341 | -451 | -605 | -1,271 | -1,705 | -2,255 | -3,751 | -4,961 | -6,355 | -13,981 | -18,755 | -24,805 | -69,905 | -153,791 | -768,955 |
