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 514,166,159, 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 | 514,166,159 | |
| -1 | -514,166,159 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 514,166,159.
Example:
1 x 514,166,159 = 514,166,159
and
-1 x -514,166,159 = 514,166,159
Notice both answers equal 514,166,159
With that explanation out of the way, let's continue. Next, we take the number 514,166,159 and divide it by 2:
514,166,159 ÷ 2 = 257,083,079.5
If the quotient is a whole number, then 2 and 257,083,079.5 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 | 514,166,159 | |
| -1 | -514,166,159 |
Now, we try dividing 514,166,159 by 3:
514,166,159 ÷ 3 = 171,388,719.6667
If the quotient is a whole number, then 3 and 171,388,719.6667 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 | 514,166,159 | |
| -1 | -514,166,159 |
Let's try dividing by 4:
514,166,159 ÷ 4 = 128,541,539.75
If the quotient is a whole number, then 4 and 128,541,539.75 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 | 514,166,159 | |
| -1 | 514,166,159 |
If you did it right, you will end up with this table:
| 1 | 13 | 83 | 113 | 1,079 | 1,469 | 4,217 | 9,379 | 54,821 | 121,927 | 350,011 | 476,521 | 4,550,143 | 6,194,773 | 39,551,243 | 514,166,159 |
| -1 | -13 | -83 | -113 | -1,079 | -1,469 | -4,217 | -9,379 | -54,821 | -121,927 | -350,011 | -476,521 | -4,550,143 | -6,194,773 | -39,551,243 | -514,166,159 |
