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 106,316,285, 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 | 106,316,285 | |
| -1 | -106,316,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 106,316,285.
Example:
1 x 106,316,285 = 106,316,285
and
-1 x -106,316,285 = 106,316,285
Notice both answers equal 106,316,285
With that explanation out of the way, let's continue. Next, we take the number 106,316,285 and divide it by 2:
106,316,285 ÷ 2 = 53,158,142.5
If the quotient is a whole number, then 2 and 53,158,142.5 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 | 106,316,285 | |
| -1 | -106,316,285 |
Now, we try dividing 106,316,285 by 3:
106,316,285 ÷ 3 = 35,438,761.6667
If the quotient is a whole number, then 3 and 35,438,761.6667 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 | 106,316,285 | |
| -1 | -106,316,285 |
Let's try dividing by 4:
106,316,285 ÷ 4 = 26,579,071.25
If the quotient is a whole number, then 4 and 26,579,071.25 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 | 106,316,285 | |
| -1 | 106,316,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 173 | 445 | 865 | 1,381 | 6,905 | 15,397 | 76,985 | 122,909 | 238,913 | 614,545 | 1,194,565 | 21,263,257 | 106,316,285 |
| -1 | -5 | -89 | -173 | -445 | -865 | -1,381 | -6,905 | -15,397 | -76,985 | -122,909 | -238,913 | -614,545 | -1,194,565 | -21,263,257 | -106,316,285 |
