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 104,500,045, 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 | 104,500,045 | |
| -1 | -104,500,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,500,045.
Example:
1 x 104,500,045 = 104,500,045
and
-1 x -104,500,045 = 104,500,045
Notice both answers equal 104,500,045
With that explanation out of the way, let's continue. Next, we take the number 104,500,045 and divide it by 2:
104,500,045 ÷ 2 = 52,250,022.5
If the quotient is a whole number, then 2 and 52,250,022.5 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 | 104,500,045 | |
| -1 | -104,500,045 |
Now, we try dividing 104,500,045 by 3:
104,500,045 ÷ 3 = 34,833,348.3333
If the quotient is a whole number, then 3 and 34,833,348.3333 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 | 104,500,045 | |
| -1 | -104,500,045 |
Let's try dividing by 4:
104,500,045 ÷ 4 = 26,125,011.25
If the quotient is a whole number, then 4 and 26,125,011.25 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 | 104,500,045 | |
| -1 | 104,500,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 127 | 635 | 1,651 | 8,255 | 12,659 | 63,295 | 164,567 | 822,835 | 1,607,693 | 8,038,465 | 20,900,009 | 104,500,045 |
| -1 | -5 | -13 | -65 | -127 | -635 | -1,651 | -8,255 | -12,659 | -63,295 | -164,567 | -822,835 | -1,607,693 | -8,038,465 | -20,900,009 | -104,500,045 |
