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 243,254,563, 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 | 243,254,563 | |
| -1 | -243,254,563 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 243,254,563.
Example:
1 x 243,254,563 = 243,254,563
and
-1 x -243,254,563 = 243,254,563
Notice both answers equal 243,254,563
With that explanation out of the way, let's continue. Next, we take the number 243,254,563 and divide it by 2:
243,254,563 ÷ 2 = 121,627,281.5
If the quotient is a whole number, then 2 and 121,627,281.5 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 | 243,254,563 | |
| -1 | -243,254,563 |
Now, we try dividing 243,254,563 by 3:
243,254,563 ÷ 3 = 81,084,854.3333
If the quotient is a whole number, then 3 and 81,084,854.3333 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 | 243,254,563 | |
| -1 | -243,254,563 |
Let's try dividing by 4:
243,254,563 ÷ 4 = 60,813,640.75
If the quotient is a whole number, then 4 and 60,813,640.75 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 | 243,254,563 | |
| -1 | 243,254,563 |
If you did it right, you will end up with this table:
| 1 | 47 | 97 | 229 | 233 | 4,559 | 10,763 | 10,951 | 22,213 | 22,601 | 53,357 | 1,044,011 | 1,062,247 | 2,507,779 | 5,175,629 | 243,254,563 |
| -1 | -47 | -97 | -229 | -233 | -4,559 | -10,763 | -10,951 | -22,213 | -22,601 | -53,357 | -1,044,011 | -1,062,247 | -2,507,779 | -5,175,629 | -243,254,563 |
