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 240,626,449, 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 | 240,626,449 | |
| -1 | -240,626,449 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 240,626,449.
Example:
1 x 240,626,449 = 240,626,449
and
-1 x -240,626,449 = 240,626,449
Notice both answers equal 240,626,449
With that explanation out of the way, let's continue. Next, we take the number 240,626,449 and divide it by 2:
240,626,449 ÷ 2 = 120,313,224.5
If the quotient is a whole number, then 2 and 120,313,224.5 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 | 240,626,449 | |
| -1 | -240,626,449 |
Now, we try dividing 240,626,449 by 3:
240,626,449 ÷ 3 = 80,208,816.3333
If the quotient is a whole number, then 3 and 80,208,816.3333 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 | 240,626,449 | |
| -1 | -240,626,449 |
Let's try dividing by 4:
240,626,449 ÷ 4 = 60,156,612.25
If the quotient is a whole number, then 4 and 60,156,612.25 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 | 240,626,449 | |
| -1 | 240,626,449 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 1,213 | 1,667 | 8,491 | 11,669 | 20,621 | 28,339 | 144,347 | 198,373 | 2,022,071 | 14,154,497 | 34,375,207 | 240,626,449 |
| -1 | -7 | -17 | -119 | -1,213 | -1,667 | -8,491 | -11,669 | -20,621 | -28,339 | -144,347 | -198,373 | -2,022,071 | -14,154,497 | -34,375,207 | -240,626,449 |
