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 240,823,445, 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 | 240,823,445 | |
| -1 | -240,823,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,823,445.
Example:
1 x 240,823,445 = 240,823,445
and
-1 x -240,823,445 = 240,823,445
Notice both answers equal 240,823,445
With that explanation out of the way, let's continue. Next, we take the number 240,823,445 and divide it by 2:
240,823,445 ÷ 2 = 120,411,722.5
If the quotient is a whole number, then 2 and 120,411,722.5 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 | 240,823,445 | |
| -1 | -240,823,445 |
Now, we try dividing 240,823,445 by 3:
240,823,445 ÷ 3 = 80,274,481.6667
If the quotient is a whole number, then 3 and 80,274,481.6667 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 | 240,823,445 | |
| -1 | -240,823,445 |
Let's try dividing by 4:
240,823,445 ÷ 4 = 60,205,861.25
If the quotient is a whole number, then 4 and 60,205,861.25 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 | 240,823,445 | |
| -1 | 240,823,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 541 | 2,705 | 5,237 | 9,197 | 26,185 | 45,985 | 89,029 | 445,145 | 2,833,217 | 14,166,085 | 48,164,689 | 240,823,445 |
| -1 | -5 | -17 | -85 | -541 | -2,705 | -5,237 | -9,197 | -26,185 | -45,985 | -89,029 | -445,145 | -2,833,217 | -14,166,085 | -48,164,689 | -240,823,445 |
