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 103,000,105, 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 | 103,000,105 | |
| -1 | -103,000,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,000,105.
Example:
1 x 103,000,105 = 103,000,105
and
-1 x -103,000,105 = 103,000,105
Notice both answers equal 103,000,105
With that explanation out of the way, let's continue. Next, we take the number 103,000,105 and divide it by 2:
103,000,105 ÷ 2 = 51,500,052.5
If the quotient is a whole number, then 2 and 51,500,052.5 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 | 103,000,105 | |
| -1 | -103,000,105 |
Now, we try dividing 103,000,105 by 3:
103,000,105 ÷ 3 = 34,333,368.3333
If the quotient is a whole number, then 3 and 34,333,368.3333 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 | 103,000,105 | |
| -1 | -103,000,105 |
Let's try dividing by 4:
103,000,105 ÷ 4 = 25,750,026.25
If the quotient is a whole number, then 4 and 25,750,026.25 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 | 103,000,105 | |
| -1 | 103,000,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 67 | 335 | 353 | 871 | 1,765 | 4,355 | 4,489 | 4,589 | 22,445 | 22,945 | 23,651 | 58,357 | 118,255 | 291,785 | 307,463 | 1,537,315 | 1,584,617 | 7,923,085 | 20,600,021 | 103,000,105 |
| -1 | -5 | -13 | -65 | -67 | -335 | -353 | -871 | -1,765 | -4,355 | -4,489 | -4,589 | -22,445 | -22,945 | -23,651 | -58,357 | -118,255 | -291,785 | -307,463 | -1,537,315 | -1,584,617 | -7,923,085 | -20,600,021 | -103,000,105 |
