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 105,866,827, 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 | 105,866,827 | |
| -1 | -105,866,827 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,866,827.
Example:
1 x 105,866,827 = 105,866,827
and
-1 x -105,866,827 = 105,866,827
Notice both answers equal 105,866,827
With that explanation out of the way, let's continue. Next, we take the number 105,866,827 and divide it by 2:
105,866,827 ÷ 2 = 52,933,413.5
If the quotient is a whole number, then 2 and 52,933,413.5 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 | 105,866,827 | |
| -1 | -105,866,827 |
Now, we try dividing 105,866,827 by 3:
105,866,827 ÷ 3 = 35,288,942.3333
If the quotient is a whole number, then 3 and 35,288,942.3333 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 | 105,866,827 | |
| -1 | -105,866,827 |
Let's try dividing by 4:
105,866,827 ÷ 4 = 26,466,706.75
If the quotient is a whole number, then 4 and 26,466,706.75 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 | 105,866,827 | |
| -1 | 105,866,827 |
If you did it right, you will end up with this table:
| 1 | 11 | 59 | 157 | 649 | 1,039 | 1,727 | 9,263 | 11,429 | 61,301 | 101,893 | 163,123 | 674,311 | 1,794,353 | 9,624,257 | 105,866,827 |
| -1 | -11 | -59 | -157 | -649 | -1,039 | -1,727 | -9,263 | -11,429 | -61,301 | -101,893 | -163,123 | -674,311 | -1,794,353 | -9,624,257 | -105,866,827 |
