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 240,622,501, 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 | 240,622,501 | |
| -1 | -240,622,501 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,622,501.
Example:
1 x 240,622,501 = 240,622,501
and
-1 x -240,622,501 = 240,622,501
Notice both answers equal 240,622,501
With that explanation out of the way, let's continue. Next, we take the number 240,622,501 and divide it by 2:
240,622,501 ÷ 2 = 120,311,250.5
If the quotient is a whole number, then 2 and 120,311,250.5 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 | 240,622,501 | |
| -1 | -240,622,501 |
Now, we try dividing 240,622,501 by 3:
240,622,501 ÷ 3 = 80,207,500.3333
If the quotient is a whole number, then 3 and 80,207,500.3333 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 | 240,622,501 | |
| -1 | -240,622,501 |
Let's try dividing by 4:
240,622,501 ÷ 4 = 60,155,625.25
If the quotient is a whole number, then 4 and 60,155,625.25 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 | 240,622,501 | |
| -1 | 240,622,501 |
If you did it right, you will end up with this table:
| 1 | 7 | 101 | 211 | 707 | 1,477 | 1,613 | 11,291 | 21,311 | 149,177 | 162,913 | 340,343 | 1,140,391 | 2,382,401 | 34,374,643 | 240,622,501 |
| -1 | -7 | -101 | -211 | -707 | -1,477 | -1,613 | -11,291 | -21,311 | -149,177 | -162,913 | -340,343 | -1,140,391 | -2,382,401 | -34,374,643 | -240,622,501 |
