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 242,543,035, 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 | 242,543,035 | |
| -1 | -242,543,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 242,543,035.
Example:
1 x 242,543,035 = 242,543,035
and
-1 x -242,543,035 = 242,543,035
Notice both answers equal 242,543,035
With that explanation out of the way, let's continue. Next, we take the number 242,543,035 and divide it by 2:
242,543,035 ÷ 2 = 121,271,517.5
If the quotient is a whole number, then 2 and 121,271,517.5 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 | 242,543,035 | |
| -1 | -242,543,035 |
Now, we try dividing 242,543,035 by 3:
242,543,035 ÷ 3 = 80,847,678.3333
If the quotient is a whole number, then 3 and 80,847,678.3333 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 | 242,543,035 | |
| -1 | -242,543,035 |
Let's try dividing by 4:
242,543,035 ÷ 4 = 60,635,758.75
If the quotient is a whole number, then 4 and 60,635,758.75 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 | 242,543,035 | |
| -1 | 242,543,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 79 | 395 | 553 | 2,765 | 87,719 | 438,595 | 614,033 | 3,070,165 | 6,929,801 | 34,649,005 | 48,508,607 | 242,543,035 |
| -1 | -5 | -7 | -35 | -79 | -395 | -553 | -2,765 | -87,719 | -438,595 | -614,033 | -3,070,165 | -6,929,801 | -34,649,005 | -48,508,607 | -242,543,035 |
