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 540,053,161, 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 | 540,053,161 | |
| -1 | -540,053,161 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 540,053,161.
Example:
1 x 540,053,161 = 540,053,161
and
-1 x -540,053,161 = 540,053,161
Notice both answers equal 540,053,161
With that explanation out of the way, let's continue. Next, we take the number 540,053,161 and divide it by 2:
540,053,161 ÷ 2 = 270,026,580.5
If the quotient is a whole number, then 2 and 270,026,580.5 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 | 540,053,161 | |
| -1 | -540,053,161 |
Now, we try dividing 540,053,161 by 3:
540,053,161 ÷ 3 = 180,017,720.3333
If the quotient is a whole number, then 3 and 180,017,720.3333 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 | 540,053,161 | |
| -1 | -540,053,161 |
Let's try dividing by 4:
540,053,161 ÷ 4 = 135,013,290.25
If the quotient is a whole number, then 4 and 135,013,290.25 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 | 540,053,161 | |
| -1 | 540,053,161 |
If you did it right, you will end up with this table:
| 1 | 17 | 101 | 151 | 1,717 | 2,083 | 2,567 | 15,251 | 35,411 | 210,383 | 259,267 | 314,533 | 3,576,511 | 5,347,061 | 31,767,833 | 540,053,161 |
| -1 | -17 | -101 | -151 | -1,717 | -2,083 | -2,567 | -15,251 | -35,411 | -210,383 | -259,267 | -314,533 | -3,576,511 | -5,347,061 | -31,767,833 | -540,053,161 |
