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 514,001,555, 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 | 514,001,555 | |
| -1 | -514,001,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 514,001,555.
Example:
1 x 514,001,555 = 514,001,555
and
-1 x -514,001,555 = 514,001,555
Notice both answers equal 514,001,555
With that explanation out of the way, let's continue. Next, we take the number 514,001,555 and divide it by 2:
514,001,555 ÷ 2 = 257,000,777.5
If the quotient is a whole number, then 2 and 257,000,777.5 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 | 514,001,555 | |
| -1 | -514,001,555 |
Now, we try dividing 514,001,555 by 3:
514,001,555 ÷ 3 = 171,333,851.6667
If the quotient is a whole number, then 3 and 171,333,851.6667 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 | 514,001,555 | |
| -1 | -514,001,555 |
Let's try dividing by 4:
514,001,555 ÷ 4 = 128,500,388.75
If the quotient is a whole number, then 4 and 128,500,388.75 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 | 514,001,555 | |
| -1 | 514,001,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 67 | 305 | 335 | 4,087 | 20,435 | 25,153 | 125,765 | 1,534,333 | 1,685,251 | 7,671,665 | 8,426,255 | 102,800,311 | 514,001,555 |
| -1 | -5 | -61 | -67 | -305 | -335 | -4,087 | -20,435 | -25,153 | -125,765 | -1,534,333 | -1,685,251 | -7,671,665 | -8,426,255 | -102,800,311 | -514,001,555 |
