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 106,610,519, 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 | 106,610,519 | |
| -1 | -106,610,519 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 106,610,519.
Example:
1 x 106,610,519 = 106,610,519
and
-1 x -106,610,519 = 106,610,519
Notice both answers equal 106,610,519
With that explanation out of the way, let's continue. Next, we take the number 106,610,519 and divide it by 2:
106,610,519 ÷ 2 = 53,305,259.5
If the quotient is a whole number, then 2 and 53,305,259.5 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 | 106,610,519 | |
| -1 | -106,610,519 |
Now, we try dividing 106,610,519 by 3:
106,610,519 ÷ 3 = 35,536,839.6667
If the quotient is a whole number, then 3 and 35,536,839.6667 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 | 106,610,519 | |
| -1 | -106,610,519 |
Let's try dividing by 4:
106,610,519 ÷ 4 = 26,652,629.75
If the quotient is a whole number, then 4 and 26,652,629.75 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 | 106,610,519 | |
| -1 | 106,610,519 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 89 | 527 | 1,513 | 2,273 | 2,759 | 38,641 | 46,903 | 70,463 | 202,297 | 1,197,871 | 3,439,049 | 6,271,207 | 106,610,519 |
| -1 | -17 | -31 | -89 | -527 | -1,513 | -2,273 | -2,759 | -38,641 | -46,903 | -70,463 | -202,297 | -1,197,871 | -3,439,049 | -6,271,207 | -106,610,519 |
