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 101,134,445, 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 | 101,134,445 | |
| -1 | -101,134,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,134,445.
Example:
1 x 101,134,445 = 101,134,445
and
-1 x -101,134,445 = 101,134,445
Notice both answers equal 101,134,445
With that explanation out of the way, let's continue. Next, we take the number 101,134,445 and divide it by 2:
101,134,445 ÷ 2 = 50,567,222.5
If the quotient is a whole number, then 2 and 50,567,222.5 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 | 101,134,445 | |
| -1 | -101,134,445 |
Now, we try dividing 101,134,445 by 3:
101,134,445 ÷ 3 = 33,711,481.6667
If the quotient is a whole number, then 3 and 33,711,481.6667 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 | 101,134,445 | |
| -1 | -101,134,445 |
Let's try dividing by 4:
101,134,445 ÷ 4 = 25,283,611.25
If the quotient is a whole number, then 4 and 25,283,611.25 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 | 101,134,445 | |
| -1 | 101,134,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 241 | 1,205 | 4,097 | 4,937 | 20,485 | 24,685 | 83,929 | 419,645 | 1,189,817 | 5,949,085 | 20,226,889 | 101,134,445 |
| -1 | -5 | -17 | -85 | -241 | -1,205 | -4,097 | -4,937 | -20,485 | -24,685 | -83,929 | -419,645 | -1,189,817 | -5,949,085 | -20,226,889 | -101,134,445 |
