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 542,443,231, 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 | 542,443,231 | |
| -1 | -542,443,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 542,443,231.
Example:
1 x 542,443,231 = 542,443,231
and
-1 x -542,443,231 = 542,443,231
Notice both answers equal 542,443,231
With that explanation out of the way, let's continue. Next, we take the number 542,443,231 and divide it by 2:
542,443,231 ÷ 2 = 271,221,615.5
If the quotient is a whole number, then 2 and 271,221,615.5 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 | 542,443,231 | |
| -1 | -542,443,231 |
Now, we try dividing 542,443,231 by 3:
542,443,231 ÷ 3 = 180,814,410.3333
If the quotient is a whole number, then 3 and 180,814,410.3333 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 | 542,443,231 | |
| -1 | -542,443,231 |
Let's try dividing by 4:
542,443,231 ÷ 4 = 135,610,807.75
If the quotient is a whole number, then 4 and 135,610,807.75 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 | 542,443,231 | |
| -1 | 542,443,231 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 211 | 319 | 2,321 | 6,119 | 8,059 | 67,309 | 88,649 | 233,711 | 1,700,449 | 2,570,821 | 18,704,939 | 49,313,021 | 542,443,231 |
| -1 | -11 | -29 | -211 | -319 | -2,321 | -6,119 | -8,059 | -67,309 | -88,649 | -233,711 | -1,700,449 | -2,570,821 | -18,704,939 | -49,313,021 | -542,443,231 |
