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 515,416,043, 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 | 515,416,043 | |
| -1 | -515,416,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 515,416,043.
Example:
1 x 515,416,043 = 515,416,043
and
-1 x -515,416,043 = 515,416,043
Notice both answers equal 515,416,043
With that explanation out of the way, let's continue. Next, we take the number 515,416,043 and divide it by 2:
515,416,043 ÷ 2 = 257,708,021.5
If the quotient is a whole number, then 2 and 257,708,021.5 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 | 515,416,043 | |
| -1 | -515,416,043 |
Now, we try dividing 515,416,043 by 3:
515,416,043 ÷ 3 = 171,805,347.6667
If the quotient is a whole number, then 3 and 171,805,347.6667 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 | 515,416,043 | |
| -1 | -515,416,043 |
Let's try dividing by 4:
515,416,043 ÷ 4 = 128,854,010.75
If the quotient is a whole number, then 4 and 128,854,010.75 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 | 515,416,043 | |
| -1 | 515,416,043 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 53 | 1,189 | 1,537 | 2,173 | 8,179 | 63,017 | 237,191 | 335,339 | 433,487 | 9,724,831 | 12,571,123 | 17,772,967 | 515,416,043 |
| -1 | -29 | -41 | -53 | -1,189 | -1,537 | -2,173 | -8,179 | -63,017 | -237,191 | -335,339 | -433,487 | -9,724,831 | -12,571,123 | -17,772,967 | -515,416,043 |
