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 541,271,155, 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 | 541,271,155 | |
| -1 | -541,271,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 541,271,155.
Example:
1 x 541,271,155 = 541,271,155
and
-1 x -541,271,155 = 541,271,155
Notice both answers equal 541,271,155
With that explanation out of the way, let's continue. Next, we take the number 541,271,155 and divide it by 2:
541,271,155 ÷ 2 = 270,635,577.5
If the quotient is a whole number, then 2 and 270,635,577.5 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 | 541,271,155 | |
| -1 | -541,271,155 |
Now, we try dividing 541,271,155 by 3:
541,271,155 ÷ 3 = 180,423,718.3333
If the quotient is a whole number, then 3 and 180,423,718.3333 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 | 541,271,155 | |
| -1 | -541,271,155 |
Let's try dividing by 4:
541,271,155 ÷ 4 = 135,317,788.75
If the quotient is a whole number, then 4 and 135,317,788.75 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 | 541,271,155 | |
| -1 | 541,271,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 97 | 173 | 485 | 865 | 6,451 | 16,781 | 32,255 | 83,905 | 625,747 | 1,116,023 | 3,128,735 | 5,580,115 | 108,254,231 | 541,271,155 |
| -1 | -5 | -97 | -173 | -485 | -865 | -6,451 | -16,781 | -32,255 | -83,905 | -625,747 | -1,116,023 | -3,128,735 | -5,580,115 | -108,254,231 | -541,271,155 |
