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 243,241,243, 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 | 243,241,243 | |
| -1 | -243,241,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 243,241,243.
Example:
1 x 243,241,243 = 243,241,243
and
-1 x -243,241,243 = 243,241,243
Notice both answers equal 243,241,243
With that explanation out of the way, let's continue. Next, we take the number 243,241,243 and divide it by 2:
243,241,243 ÷ 2 = 121,620,621.5
If the quotient is a whole number, then 2 and 121,620,621.5 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 | 243,241,243 | |
| -1 | -243,241,243 |
Now, we try dividing 243,241,243 by 3:
243,241,243 ÷ 3 = 81,080,414.3333
If the quotient is a whole number, then 3 and 81,080,414.3333 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 | 243,241,243 | |
| -1 | -243,241,243 |
Let's try dividing by 4:
243,241,243 ÷ 4 = 60,810,310.75
If the quotient is a whole number, then 4 and 60,810,310.75 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 | 243,241,243 | |
| -1 | 243,241,243 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 71 | 139 | 497 | 503 | 973 | 3,479 | 3,521 | 6,811 | 9,869 | 24,647 | 35,713 | 69,083 | 69,917 | 249,991 | 483,581 | 489,419 | 1,749,937 | 3,425,933 | 4,964,107 | 34,748,749 | 243,241,243 |
| -1 | -7 | -49 | -71 | -139 | -497 | -503 | -973 | -3,479 | -3,521 | -6,811 | -9,869 | -24,647 | -35,713 | -69,083 | -69,917 | -249,991 | -483,581 | -489,419 | -1,749,937 | -3,425,933 | -4,964,107 | -34,748,749 | -243,241,243 |
