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 243,254,561, 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 | 243,254,561 | |
| -1 | -243,254,561 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 243,254,561.
Example:
1 x 243,254,561 = 243,254,561
and
-1 x -243,254,561 = 243,254,561
Notice both answers equal 243,254,561
With that explanation out of the way, let's continue. Next, we take the number 243,254,561 and divide it by 2:
243,254,561 ÷ 2 = 121,627,280.5
If the quotient is a whole number, then 2 and 121,627,280.5 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 | 243,254,561 | |
| -1 | -243,254,561 |
Now, we try dividing 243,254,561 by 3:
243,254,561 ÷ 3 = 81,084,853.6667
If the quotient is a whole number, then 3 and 81,084,853.6667 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 | 243,254,561 | |
| -1 | -243,254,561 |
Let's try dividing by 4:
243,254,561 ÷ 4 = 60,813,640.25
If the quotient is a whole number, then 4 and 60,813,640.25 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 | 243,254,561 | |
| -1 | 243,254,561 |
If you did it right, you will end up with this table:
| 1 | 11 | 101 | 373 | 587 | 1,111 | 4,103 | 6,457 | 37,673 | 59,287 | 218,951 | 414,403 | 652,157 | 2,408,461 | 22,114,051 | 243,254,561 |
| -1 | -11 | -101 | -373 | -587 | -1,111 | -4,103 | -6,457 | -37,673 | -59,287 | -218,951 | -414,403 | -652,157 | -2,408,461 | -22,114,051 | -243,254,561 |
