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 514,263,185, 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 | 514,263,185 | |
| -1 | -514,263,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 514,263,185.
Example:
1 x 514,263,185 = 514,263,185
and
-1 x -514,263,185 = 514,263,185
Notice both answers equal 514,263,185
With that explanation out of the way, let's continue. Next, we take the number 514,263,185 and divide it by 2:
514,263,185 ÷ 2 = 257,131,592.5
If the quotient is a whole number, then 2 and 257,131,592.5 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 | 514,263,185 | |
| -1 | -514,263,185 |
Now, we try dividing 514,263,185 by 3:
514,263,185 ÷ 3 = 171,421,061.6667
If the quotient is a whole number, then 3 and 171,421,061.6667 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 | 514,263,185 | |
| -1 | -514,263,185 |
Let's try dividing by 4:
514,263,185 ÷ 4 = 128,565,796.25
If the quotient is a whole number, then 4 and 128,565,796.25 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 | 514,263,185 | |
| -1 | 514,263,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 37 | 155 | 185 | 1,147 | 5,735 | 89,671 | 448,355 | 2,779,801 | 3,317,827 | 13,899,005 | 16,589,135 | 102,852,637 | 514,263,185 |
| -1 | -5 | -31 | -37 | -155 | -185 | -1,147 | -5,735 | -89,671 | -448,355 | -2,779,801 | -3,317,827 | -13,899,005 | -16,589,135 | -102,852,637 | -514,263,185 |
