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 314,503,447, 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 | 314,503,447 | |
| -1 | -314,503,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 314,503,447.
Example:
1 x 314,503,447 = 314,503,447
and
-1 x -314,503,447 = 314,503,447
Notice both answers equal 314,503,447
With that explanation out of the way, let's continue. Next, we take the number 314,503,447 and divide it by 2:
314,503,447 ÷ 2 = 157,251,723.5
If the quotient is a whole number, then 2 and 157,251,723.5 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 | 314,503,447 | |
| -1 | -314,503,447 |
Now, we try dividing 314,503,447 by 3:
314,503,447 ÷ 3 = 104,834,482.3333
If the quotient is a whole number, then 3 and 104,834,482.3333 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 | 314,503,447 | |
| -1 | -314,503,447 |
Let's try dividing by 4:
314,503,447 ÷ 4 = 78,625,861.75
If the quotient is a whole number, then 4 and 78,625,861.75 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 | 314,503,447 | |
| -1 | 314,503,447 |
If you did it right, you will end up with this table:
| 1 | 19 | 163 | 173 | 587 | 3,097 | 3,287 | 11,153 | 28,199 | 95,681 | 101,551 | 535,781 | 1,817,939 | 1,929,469 | 16,552,813 | 314,503,447 |
| -1 | -19 | -163 | -173 | -587 | -3,097 | -3,287 | -11,153 | -28,199 | -95,681 | -101,551 | -535,781 | -1,817,939 | -1,929,469 | -16,552,813 | -314,503,447 |
