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 774,446,705, 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 | 774,446,705 | |
| -1 | -774,446,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 774,446,705.
Example:
1 x 774,446,705 = 774,446,705
and
-1 x -774,446,705 = 774,446,705
Notice both answers equal 774,446,705
With that explanation out of the way, let's continue. Next, we take the number 774,446,705 and divide it by 2:
774,446,705 ÷ 2 = 387,223,352.5
If the quotient is a whole number, then 2 and 387,223,352.5 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 | 774,446,705 | |
| -1 | -774,446,705 |
Now, we try dividing 774,446,705 by 3:
774,446,705 ÷ 3 = 258,148,901.6667
If the quotient is a whole number, then 3 and 258,148,901.6667 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 | 774,446,705 | |
| -1 | -774,446,705 |
Let's try dividing by 4:
774,446,705 ÷ 4 = 193,611,676.25
If the quotient is a whole number, then 4 and 193,611,676.25 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 | 774,446,705 | |
| -1 | 774,446,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 349 | 379 | 1,171 | 1,745 | 1,895 | 5,855 | 132,271 | 408,679 | 443,809 | 661,355 | 2,043,395 | 2,219,045 | 154,889,341 | 774,446,705 |
| -1 | -5 | -349 | -379 | -1,171 | -1,745 | -1,895 | -5,855 | -132,271 | -408,679 | -443,809 | -661,355 | -2,043,395 | -2,219,045 | -154,889,341 | -774,446,705 |
