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 243,314,225, 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 | 243,314,225 | |
| -1 | -243,314,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 243,314,225.
Example:
1 x 243,314,225 = 243,314,225
and
-1 x -243,314,225 = 243,314,225
Notice both answers equal 243,314,225
With that explanation out of the way, let's continue. Next, we take the number 243,314,225 and divide it by 2:
243,314,225 ÷ 2 = 121,657,112.5
If the quotient is a whole number, then 2 and 121,657,112.5 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 | 243,314,225 | |
| -1 | -243,314,225 |
Now, we try dividing 243,314,225 by 3:
243,314,225 ÷ 3 = 81,104,741.6667
If the quotient is a whole number, then 3 and 81,104,741.6667 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 | 243,314,225 | |
| -1 | -243,314,225 |
Let's try dividing by 4:
243,314,225 ÷ 4 = 60,828,556.25
If the quotient is a whole number, then 4 and 60,828,556.25 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 | 243,314,225 | |
| -1 | 243,314,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 1,925 | 126,397 | 631,985 | 884,779 | 1,390,367 | 3,159,925 | 4,423,895 | 6,951,835 | 9,732,569 | 22,119,475 | 34,759,175 | 48,662,845 | 243,314,225 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -1,925 | -126,397 | -631,985 | -884,779 | -1,390,367 | -3,159,925 | -4,423,895 | -6,951,835 | -9,732,569 | -22,119,475 | -34,759,175 | -48,662,845 | -243,314,225 |
