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 772,744,285, 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 | 772,744,285 | |
| -1 | -772,744,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 772,744,285.
Example:
1 x 772,744,285 = 772,744,285
and
-1 x -772,744,285 = 772,744,285
Notice both answers equal 772,744,285
With that explanation out of the way, let's continue. Next, we take the number 772,744,285 and divide it by 2:
772,744,285 ÷ 2 = 386,372,142.5
If the quotient is a whole number, then 2 and 386,372,142.5 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 | 772,744,285 | |
| -1 | -772,744,285 |
Now, we try dividing 772,744,285 by 3:
772,744,285 ÷ 3 = 257,581,428.3333
If the quotient is a whole number, then 3 and 257,581,428.3333 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 | 772,744,285 | |
| -1 | -772,744,285 |
Let's try dividing by 4:
772,744,285 ÷ 4 = 193,186,071.25
If the quotient is a whole number, then 4 and 193,186,071.25 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 | 772,744,285 | |
| -1 | 772,744,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 113 | 155 | 565 | 3,503 | 17,515 | 44,119 | 220,595 | 1,367,689 | 4,985,447 | 6,838,445 | 24,927,235 | 154,548,857 | 772,744,285 |
| -1 | -5 | -31 | -113 | -155 | -565 | -3,503 | -17,515 | -44,119 | -220,595 | -1,367,689 | -4,985,447 | -6,838,445 | -24,927,235 | -154,548,857 | -772,744,285 |
