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 104,641,355, 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 | 104,641,355 | |
| -1 | -104,641,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,641,355.
Example:
1 x 104,641,355 = 104,641,355
and
-1 x -104,641,355 = 104,641,355
Notice both answers equal 104,641,355
With that explanation out of the way, let's continue. Next, we take the number 104,641,355 and divide it by 2:
104,641,355 ÷ 2 = 52,320,677.5
If the quotient is a whole number, then 2 and 52,320,677.5 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 | 104,641,355 | |
| -1 | -104,641,355 |
Now, we try dividing 104,641,355 by 3:
104,641,355 ÷ 3 = 34,880,451.6667
If the quotient is a whole number, then 3 and 34,880,451.6667 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 | 104,641,355 | |
| -1 | -104,641,355 |
Let's try dividing by 4:
104,641,355 ÷ 4 = 26,160,338.75
If the quotient is a whole number, then 4 and 26,160,338.75 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 | 104,641,355 | |
| -1 | 104,641,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 229,981 | 1,149,905 | 1,609,867 | 2,989,753 | 8,049,335 | 14,948,765 | 20,928,271 | 104,641,355 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -229,981 | -1,149,905 | -1,609,867 | -2,989,753 | -8,049,335 | -14,948,765 | -20,928,271 | -104,641,355 |
