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 314,103,115, 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 | 314,103,115 | |
| -1 | -314,103,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 314,103,115.
Example:
1 x 314,103,115 = 314,103,115
and
-1 x -314,103,115 = 314,103,115
Notice both answers equal 314,103,115
With that explanation out of the way, let's continue. Next, we take the number 314,103,115 and divide it by 2:
314,103,115 ÷ 2 = 157,051,557.5
If the quotient is a whole number, then 2 and 157,051,557.5 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 | 314,103,115 | |
| -1 | -314,103,115 |
Now, we try dividing 314,103,115 by 3:
314,103,115 ÷ 3 = 104,701,038.3333
If the quotient is a whole number, then 3 and 104,701,038.3333 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 | 314,103,115 | |
| -1 | -314,103,115 |
Let's try dividing by 4:
314,103,115 ÷ 4 = 78,525,778.75
If the quotient is a whole number, then 4 and 78,525,778.75 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 | 314,103,115 | |
| -1 | 314,103,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 283 | 1,415 | 4,723 | 13,301 | 23,615 | 66,505 | 221,981 | 1,109,905 | 1,336,609 | 6,683,045 | 62,820,623 | 314,103,115 |
| -1 | -5 | -47 | -235 | -283 | -1,415 | -4,723 | -13,301 | -23,615 | -66,505 | -221,981 | -1,109,905 | -1,336,609 | -6,683,045 | -62,820,623 | -314,103,115 |
