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 503,400,149, 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 | 503,400,149 | |
| -1 | -503,400,149 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 503,400,149.
Example:
1 x 503,400,149 = 503,400,149
and
-1 x -503,400,149 = 503,400,149
Notice both answers equal 503,400,149
With that explanation out of the way, let's continue. Next, we take the number 503,400,149 and divide it by 2:
503,400,149 ÷ 2 = 251,700,074.5
If the quotient is a whole number, then 2 and 251,700,074.5 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 | 503,400,149 | |
| -1 | -503,400,149 |
Now, we try dividing 503,400,149 by 3:
503,400,149 ÷ 3 = 167,800,049.6667
If the quotient is a whole number, then 3 and 167,800,049.6667 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 | 503,400,149 | |
| -1 | -503,400,149 |
Let's try dividing by 4:
503,400,149 ÷ 4 = 125,850,037.25
If the quotient is a whole number, then 4 and 125,850,037.25 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 | 503,400,149 | |
| -1 | 503,400,149 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 739 | 4,231 | 5,173 | 16,997 | 29,617 | 97,313 | 118,979 | 681,191 | 3,126,709 | 21,886,963 | 71,914,307 | 503,400,149 |
| -1 | -7 | -23 | -161 | -739 | -4,231 | -5,173 | -16,997 | -29,617 | -97,313 | -118,979 | -681,191 | -3,126,709 | -21,886,963 | -71,914,307 | -503,400,149 |
