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 771,146,333, 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 | 771,146,333 | |
| -1 | -771,146,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 771,146,333.
Example:
1 x 771,146,333 = 771,146,333
and
-1 x -771,146,333 = 771,146,333
Notice both answers equal 771,146,333
With that explanation out of the way, let's continue. Next, we take the number 771,146,333 and divide it by 2:
771,146,333 ÷ 2 = 385,573,166.5
If the quotient is a whole number, then 2 and 385,573,166.5 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 | 771,146,333 | |
| -1 | -771,146,333 |
Now, we try dividing 771,146,333 by 3:
771,146,333 ÷ 3 = 257,048,777.6667
If the quotient is a whole number, then 3 and 257,048,777.6667 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 | 771,146,333 | |
| -1 | -771,146,333 |
Let's try dividing by 4:
771,146,333 ÷ 4 = 192,786,583.25
If the quotient is a whole number, then 4 and 192,786,583.25 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 | 771,146,333 | |
| -1 | 771,146,333 |
If you did it right, you will end up with this table:
| 1 | 17 | 109 | 281 | 1,481 | 1,853 | 4,777 | 25,177 | 30,629 | 161,429 | 416,161 | 520,693 | 2,744,293 | 7,074,737 | 45,361,549 | 771,146,333 |
| -1 | -17 | -109 | -281 | -1,481 | -1,853 | -4,777 | -25,177 | -30,629 | -161,429 | -416,161 | -520,693 | -2,744,293 | -7,074,737 | -45,361,549 | -771,146,333 |
