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 314,504,461, 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 | 314,504,461 | |
| -1 | -314,504,461 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 314,504,461.
Example:
1 x 314,504,461 = 314,504,461
and
-1 x -314,504,461 = 314,504,461
Notice both answers equal 314,504,461
With that explanation out of the way, let's continue. Next, we take the number 314,504,461 and divide it by 2:
314,504,461 ÷ 2 = 157,252,230.5
If the quotient is a whole number, then 2 and 157,252,230.5 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 | 314,504,461 | |
| -1 | -314,504,461 |
Now, we try dividing 314,504,461 by 3:
314,504,461 ÷ 3 = 104,834,820.3333
If the quotient is a whole number, then 3 and 104,834,820.3333 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 | 314,504,461 | |
| -1 | -314,504,461 |
Let's try dividing by 4:
314,504,461 ÷ 4 = 78,626,115.25
If the quotient is a whole number, then 4 and 78,626,115.25 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 | 314,504,461 | |
| -1 | 314,504,461 |
If you did it right, you will end up with this table:
| 1 | 23 | 137 | 151 | 661 | 3,151 | 3,473 | 15,203 | 20,687 | 90,557 | 99,811 | 475,801 | 2,082,811 | 2,295,653 | 13,674,107 | 314,504,461 |
| -1 | -23 | -137 | -151 | -661 | -3,151 | -3,473 | -15,203 | -20,687 | -90,557 | -99,811 | -475,801 | -2,082,811 | -2,295,653 | -13,674,107 | -314,504,461 |
