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 101,045,195, 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 | 101,045,195 | |
| -1 | -101,045,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,045,195.
Example:
1 x 101,045,195 = 101,045,195
and
-1 x -101,045,195 = 101,045,195
Notice both answers equal 101,045,195
With that explanation out of the way, let's continue. Next, we take the number 101,045,195 and divide it by 2:
101,045,195 ÷ 2 = 50,522,597.5
If the quotient is a whole number, then 2 and 50,522,597.5 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 | 101,045,195 | |
| -1 | -101,045,195 |
Now, we try dividing 101,045,195 by 3:
101,045,195 ÷ 3 = 33,681,731.6667
If the quotient is a whole number, then 3 and 33,681,731.6667 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 | 101,045,195 | |
| -1 | -101,045,195 |
Let's try dividing by 4:
101,045,195 ÷ 4 = 25,261,298.75
If the quotient is a whole number, then 4 and 25,261,298.75 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 | 101,045,195 | |
| -1 | 101,045,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 487 | 2,435 | 2,441 | 8,279 | 12,205 | 41,395 | 41,497 | 207,485 | 1,188,767 | 5,943,835 | 20,209,039 | 101,045,195 |
| -1 | -5 | -17 | -85 | -487 | -2,435 | -2,441 | -8,279 | -12,205 | -41,395 | -41,497 | -207,485 | -1,188,767 | -5,943,835 | -20,209,039 | -101,045,195 |
