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 242,176,433, 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 | 242,176,433 | |
| -1 | -242,176,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,176,433.
Example:
1 x 242,176,433 = 242,176,433
and
-1 x -242,176,433 = 242,176,433
Notice both answers equal 242,176,433
With that explanation out of the way, let's continue. Next, we take the number 242,176,433 and divide it by 2:
242,176,433 ÷ 2 = 121,088,216.5
If the quotient is a whole number, then 2 and 121,088,216.5 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 | 242,176,433 | |
| -1 | -242,176,433 |
Now, we try dividing 242,176,433 by 3:
242,176,433 ÷ 3 = 80,725,477.6667
If the quotient is a whole number, then 3 and 80,725,477.6667 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 | 242,176,433 | |
| -1 | -242,176,433 |
Let's try dividing by 4:
242,176,433 ÷ 4 = 60,544,108.25
If the quotient is a whole number, then 4 and 60,544,108.25 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 | 242,176,433 | |
| -1 | 242,176,433 |
If you did it right, you will end up with this table:
| 1 | 31 | 37 | 199 | 1,061 | 1,147 | 6,169 | 7,363 | 32,891 | 39,257 | 211,139 | 228,253 | 1,216,967 | 6,545,309 | 7,812,143 | 242,176,433 |
| -1 | -31 | -37 | -199 | -1,061 | -1,147 | -6,169 | -7,363 | -32,891 | -39,257 | -211,139 | -228,253 | -1,216,967 | -6,545,309 | -7,812,143 | -242,176,433 |
