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 101,542,513, 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 | 101,542,513 | |
| -1 | -101,542,513 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,542,513.
Example:
1 x 101,542,513 = 101,542,513
and
-1 x -101,542,513 = 101,542,513
Notice both answers equal 101,542,513
With that explanation out of the way, let's continue. Next, we take the number 101,542,513 and divide it by 2:
101,542,513 ÷ 2 = 50,771,256.5
If the quotient is a whole number, then 2 and 50,771,256.5 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 | 101,542,513 | |
| -1 | -101,542,513 |
Now, we try dividing 101,542,513 by 3:
101,542,513 ÷ 3 = 33,847,504.3333
If the quotient is a whole number, then 3 and 33,847,504.3333 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 | 101,542,513 | |
| -1 | -101,542,513 |
Let's try dividing by 4:
101,542,513 ÷ 4 = 25,385,628.25
If the quotient is a whole number, then 4 and 25,385,628.25 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 | 101,542,513 | |
| -1 | 101,542,513 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 167 | 761 | 799 | 2,839 | 7,849 | 12,937 | 35,767 | 127,087 | 133,433 | 608,039 | 2,160,479 | 5,973,089 | 101,542,513 |
| -1 | -17 | -47 | -167 | -761 | -799 | -2,839 | -7,849 | -12,937 | -35,767 | -127,087 | -133,433 | -608,039 | -2,160,479 | -5,973,089 | -101,542,513 |
