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 240,865,835, 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 | 240,865,835 | |
| -1 | -240,865,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,865,835.
Example:
1 x 240,865,835 = 240,865,835
and
-1 x -240,865,835 = 240,865,835
Notice both answers equal 240,865,835
With that explanation out of the way, let's continue. Next, we take the number 240,865,835 and divide it by 2:
240,865,835 ÷ 2 = 120,432,917.5
If the quotient is a whole number, then 2 and 120,432,917.5 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 | 240,865,835 | |
| -1 | -240,865,835 |
Now, we try dividing 240,865,835 by 3:
240,865,835 ÷ 3 = 80,288,611.6667
If the quotient is a whole number, then 3 and 80,288,611.6667 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 | 240,865,835 | |
| -1 | -240,865,835 |
Let's try dividing by 4:
240,865,835 ÷ 4 = 60,216,458.75
If the quotient is a whole number, then 4 and 60,216,458.75 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 | 240,865,835 | |
| -1 | 240,865,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 235 | 329 | 1,645 | 146,423 | 732,115 | 1,024,961 | 5,124,805 | 6,881,881 | 34,409,405 | 48,173,167 | 240,865,835 |
| -1 | -5 | -7 | -35 | -47 | -235 | -329 | -1,645 | -146,423 | -732,115 | -1,024,961 | -5,124,805 | -6,881,881 | -34,409,405 | -48,173,167 | -240,865,835 |
