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 105,152,327, 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 | 105,152,327 | |
| -1 | -105,152,327 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,152,327.
Example:
1 x 105,152,327 = 105,152,327
and
-1 x -105,152,327 = 105,152,327
Notice both answers equal 105,152,327
With that explanation out of the way, let's continue. Next, we take the number 105,152,327 and divide it by 2:
105,152,327 ÷ 2 = 52,576,163.5
If the quotient is a whole number, then 2 and 52,576,163.5 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 | 105,152,327 | |
| -1 | -105,152,327 |
Now, we try dividing 105,152,327 by 3:
105,152,327 ÷ 3 = 35,050,775.6667
If the quotient is a whole number, then 3 and 35,050,775.6667 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 | 105,152,327 | |
| -1 | -105,152,327 |
Let's try dividing by 4:
105,152,327 ÷ 4 = 26,288,081.75
If the quotient is a whole number, then 4 and 26,288,081.75 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 | 105,152,327 | |
| -1 | 105,152,327 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 119 | 133 | 323 | 2,261 | 46,507 | 325,549 | 790,619 | 883,633 | 5,534,333 | 6,185,431 | 15,021,761 | 105,152,327 |
| -1 | -7 | -17 | -19 | -119 | -133 | -323 | -2,261 | -46,507 | -325,549 | -790,619 | -883,633 | -5,534,333 | -6,185,431 | -15,021,761 | -105,152,327 |
