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 503,111,141, 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 | 503,111,141 | |
| -1 | -503,111,141 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 503,111,141.
Example:
1 x 503,111,141 = 503,111,141
and
-1 x -503,111,141 = 503,111,141
Notice both answers equal 503,111,141
With that explanation out of the way, let's continue. Next, we take the number 503,111,141 and divide it by 2:
503,111,141 ÷ 2 = 251,555,570.5
If the quotient is a whole number, then 2 and 251,555,570.5 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 | 503,111,141 | |
| -1 | -503,111,141 |
Now, we try dividing 503,111,141 by 3:
503,111,141 ÷ 3 = 167,703,713.6667
If the quotient is a whole number, then 3 and 167,703,713.6667 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 | 503,111,141 | |
| -1 | -503,111,141 |
Let's try dividing by 4:
503,111,141 ÷ 4 = 125,777,785.25
If the quotient is a whole number, then 4 and 125,777,785.25 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 | 503,111,141 | |
| -1 | 503,111,141 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 169 | 221 | 289 | 2,873 | 3,757 | 10,301 | 48,841 | 133,913 | 175,117 | 1,740,869 | 2,276,521 | 2,976,989 | 29,594,773 | 38,700,857 | 503,111,141 |
| -1 | -13 | -17 | -169 | -221 | -289 | -2,873 | -3,757 | -10,301 | -48,841 | -133,913 | -175,117 | -1,740,869 | -2,276,521 | -2,976,989 | -29,594,773 | -38,700,857 | -503,111,141 |
