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 101,351,315, 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 | 101,351,315 | |
| -1 | -101,351,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,351,315.
Example:
1 x 101,351,315 = 101,351,315
and
-1 x -101,351,315 = 101,351,315
Notice both answers equal 101,351,315
With that explanation out of the way, let's continue. Next, we take the number 101,351,315 and divide it by 2:
101,351,315 ÷ 2 = 50,675,657.5
If the quotient is a whole number, then 2 and 50,675,657.5 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 | 101,351,315 | |
| -1 | -101,351,315 |
Now, we try dividing 101,351,315 by 3:
101,351,315 ÷ 3 = 33,783,771.6667
If the quotient is a whole number, then 3 and 33,783,771.6667 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 | 101,351,315 | |
| -1 | -101,351,315 |
Let's try dividing by 4:
101,351,315 ÷ 4 = 25,337,828.75
If the quotient is a whole number, then 4 and 25,337,828.75 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 | 101,351,315 | |
| -1 | 101,351,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 1,193 | 1,307 | 5,965 | 6,535 | 15,509 | 16,991 | 77,545 | 84,955 | 1,559,251 | 7,796,255 | 20,270,263 | 101,351,315 |
| -1 | -5 | -13 | -65 | -1,193 | -1,307 | -5,965 | -6,535 | -15,509 | -16,991 | -77,545 | -84,955 | -1,559,251 | -7,796,255 | -20,270,263 | -101,351,315 |
