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 240,422,545, 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 | 240,422,545 | |
| -1 | -240,422,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,422,545.
Example:
1 x 240,422,545 = 240,422,545
and
-1 x -240,422,545 = 240,422,545
Notice both answers equal 240,422,545
With that explanation out of the way, let's continue. Next, we take the number 240,422,545 and divide it by 2:
240,422,545 ÷ 2 = 120,211,272.5
If the quotient is a whole number, then 2 and 120,211,272.5 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 | 240,422,545 | |
| -1 | -240,422,545 |
Now, we try dividing 240,422,545 by 3:
240,422,545 ÷ 3 = 80,140,848.3333
If the quotient is a whole number, then 3 and 80,140,848.3333 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 | 240,422,545 | |
| -1 | -240,422,545 |
Let's try dividing by 4:
240,422,545 ÷ 4 = 60,105,636.25
If the quotient is a whole number, then 4 and 60,105,636.25 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 | 240,422,545 | |
| -1 | 240,422,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,543 | 2,833 | 7,715 | 14,165 | 16,973 | 31,163 | 84,865 | 155,815 | 4,371,319 | 21,856,595 | 48,084,509 | 240,422,545 |
| -1 | -5 | -11 | -55 | -1,543 | -2,833 | -7,715 | -14,165 | -16,973 | -31,163 | -84,865 | -155,815 | -4,371,319 | -21,856,595 | -48,084,509 | -240,422,545 |
