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 104,263,445, 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 | 104,263,445 | |
| -1 | -104,263,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,263,445.
Example:
1 x 104,263,445 = 104,263,445
and
-1 x -104,263,445 = 104,263,445
Notice both answers equal 104,263,445
With that explanation out of the way, let's continue. Next, we take the number 104,263,445 and divide it by 2:
104,263,445 ÷ 2 = 52,131,722.5
If the quotient is a whole number, then 2 and 52,131,722.5 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 | 104,263,445 | |
| -1 | -104,263,445 |
Now, we try dividing 104,263,445 by 3:
104,263,445 ÷ 3 = 34,754,481.6667
If the quotient is a whole number, then 3 and 34,754,481.6667 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 | 104,263,445 | |
| -1 | -104,263,445 |
Let's try dividing by 4:
104,263,445 ÷ 4 = 26,065,861.25
If the quotient is a whole number, then 4 and 26,065,861.25 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 | 104,263,445 | |
| -1 | 104,263,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 145,823 | 729,115 | 1,604,053 | 1,895,699 | 8,020,265 | 9,478,495 | 20,852,689 | 104,263,445 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -145,823 | -729,115 | -1,604,053 | -1,895,699 | -8,020,265 | -9,478,495 | -20,852,689 | -104,263,445 |
