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 542,208,545, 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 | 542,208,545 | |
| -1 | -542,208,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 542,208,545.
Example:
1 x 542,208,545 = 542,208,545
and
-1 x -542,208,545 = 542,208,545
Notice both answers equal 542,208,545
With that explanation out of the way, let's continue. Next, we take the number 542,208,545 and divide it by 2:
542,208,545 ÷ 2 = 271,104,272.5
If the quotient is a whole number, then 2 and 271,104,272.5 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 | 542,208,545 | |
| -1 | -542,208,545 |
Now, we try dividing 542,208,545 by 3:
542,208,545 ÷ 3 = 180,736,181.6667
If the quotient is a whole number, then 3 and 180,736,181.6667 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 | 542,208,545 | |
| -1 | -542,208,545 |
Let's try dividing by 4:
542,208,545 ÷ 4 = 135,552,136.25
If the quotient is a whole number, then 4 and 135,552,136.25 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 | 542,208,545 | |
| -1 | 542,208,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 185 | 239 | 1,195 | 8,843 | 12,263 | 44,215 | 61,315 | 453,731 | 2,268,655 | 2,930,857 | 14,654,285 | 108,441,709 | 542,208,545 |
| -1 | -5 | -37 | -185 | -239 | -1,195 | -8,843 | -12,263 | -44,215 | -61,315 | -453,731 | -2,268,655 | -2,930,857 | -14,654,285 | -108,441,709 | -542,208,545 |
