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 262,847,843, 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 | 262,847,843 | |
| -1 | -262,847,843 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 262,847,843.
Example:
1 x 262,847,843 = 262,847,843
and
-1 x -262,847,843 = 262,847,843
Notice both answers equal 262,847,843
With that explanation out of the way, let's continue. Next, we take the number 262,847,843 and divide it by 2:
262,847,843 ÷ 2 = 131,423,921.5
If the quotient is a whole number, then 2 and 131,423,921.5 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 | 262,847,843 | |
| -1 | -262,847,843 |
Now, we try dividing 262,847,843 by 3:
262,847,843 ÷ 3 = 87,615,947.6667
If the quotient is a whole number, then 3 and 87,615,947.6667 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 | 262,847,843 | |
| -1 | -262,847,843 |
Let's try dividing by 4:
262,847,843 ÷ 4 = 65,711,960.75
If the quotient is a whole number, then 4 and 65,711,960.75 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 | 262,847,843 | |
| -1 | 262,847,843 |
If you did it right, you will end up with this table:
| 1 | 19 | 41 | 569 | 593 | 779 | 10,811 | 11,267 | 23,329 | 24,313 | 337,417 | 443,251 | 461,947 | 6,410,923 | 13,834,097 | 262,847,843 |
| -1 | -19 | -41 | -569 | -593 | -779 | -10,811 | -11,267 | -23,329 | -24,313 | -337,417 | -443,251 | -461,947 | -6,410,923 | -13,834,097 | -262,847,843 |
