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 240,771,125, 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 | 240,771,125 | |
| -1 | -240,771,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,771,125.
Example:
1 x 240,771,125 = 240,771,125
and
-1 x -240,771,125 = 240,771,125
Notice both answers equal 240,771,125
With that explanation out of the way, let's continue. Next, we take the number 240,771,125 and divide it by 2:
240,771,125 ÷ 2 = 120,385,562.5
If the quotient is a whole number, then 2 and 120,385,562.5 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 | 240,771,125 | |
| -1 | -240,771,125 |
Now, we try dividing 240,771,125 by 3:
240,771,125 ÷ 3 = 80,257,041.6667
If the quotient is a whole number, then 3 and 80,257,041.6667 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 | 240,771,125 | |
| -1 | -240,771,125 |
Let's try dividing by 4:
240,771,125 ÷ 4 = 60,192,781.25
If the quotient is a whole number, then 4 and 60,192,781.25 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 | 240,771,125 | |
| -1 | 240,771,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 275,167 | 1,375,835 | 1,926,169 | 6,879,175 | 9,630,845 | 34,395,875 | 48,154,225 | 240,771,125 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -275,167 | -1,375,835 | -1,926,169 | -6,879,175 | -9,630,845 | -34,395,875 | -48,154,225 | -240,771,125 |
