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 114,852,647, 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 | 114,852,647 | |
| -1 | -114,852,647 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 114,852,647.
Example:
1 x 114,852,647 = 114,852,647
and
-1 x -114,852,647 = 114,852,647
Notice both answers equal 114,852,647
With that explanation out of the way, let's continue. Next, we take the number 114,852,647 and divide it by 2:
114,852,647 ÷ 2 = 57,426,323.5
If the quotient is a whole number, then 2 and 57,426,323.5 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 | 114,852,647 | |
| -1 | -114,852,647 |
Now, we try dividing 114,852,647 by 3:
114,852,647 ÷ 3 = 38,284,215.6667
If the quotient is a whole number, then 3 and 38,284,215.6667 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 | 114,852,647 | |
| -1 | -114,852,647 |
Let's try dividing by 4:
114,852,647 ÷ 4 = 28,713,161.75
If the quotient is a whole number, then 4 and 28,713,161.75 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 | 114,852,647 | |
| -1 | 114,852,647 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 241 | 1,687 | 3,133 | 5,237 | 21,931 | 36,659 | 68,081 | 476,567 | 1,262,117 | 8,834,819 | 16,407,521 | 114,852,647 |
| -1 | -7 | -13 | -91 | -241 | -1,687 | -3,133 | -5,237 | -21,931 | -36,659 | -68,081 | -476,567 | -1,262,117 | -8,834,819 | -16,407,521 | -114,852,647 |
