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 101,351,285, 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 | 101,351,285 | |
| -1 | -101,351,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,351,285.
Example:
1 x 101,351,285 = 101,351,285
and
-1 x -101,351,285 = 101,351,285
Notice both answers equal 101,351,285
With that explanation out of the way, let's continue. Next, we take the number 101,351,285 and divide it by 2:
101,351,285 ÷ 2 = 50,675,642.5
If the quotient is a whole number, then 2 and 50,675,642.5 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 | 101,351,285 | |
| -1 | -101,351,285 |
Now, we try dividing 101,351,285 by 3:
101,351,285 ÷ 3 = 33,783,761.6667
If the quotient is a whole number, then 3 and 33,783,761.6667 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 | 101,351,285 | |
| -1 | -101,351,285 |
Let's try dividing by 4:
101,351,285 ÷ 4 = 25,337,821.25
If the quotient is a whole number, then 4 and 25,337,821.25 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 | 101,351,285 | |
| -1 | 101,351,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 191 | 955 | 1,337 | 6,685 | 15,161 | 75,805 | 106,127 | 530,635 | 2,895,751 | 14,478,755 | 20,270,257 | 101,351,285 |
| -1 | -5 | -7 | -35 | -191 | -955 | -1,337 | -6,685 | -15,161 | -75,805 | -106,127 | -530,635 | -2,895,751 | -14,478,755 | -20,270,257 | -101,351,285 |
