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 104,974,765, 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 | 104,974,765 | |
| -1 | -104,974,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,974,765.
Example:
1 x 104,974,765 = 104,974,765
and
-1 x -104,974,765 = 104,974,765
Notice both answers equal 104,974,765
With that explanation out of the way, let's continue. Next, we take the number 104,974,765 and divide it by 2:
104,974,765 ÷ 2 = 52,487,382.5
If the quotient is a whole number, then 2 and 52,487,382.5 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 | 104,974,765 | |
| -1 | -104,974,765 |
Now, we try dividing 104,974,765 by 3:
104,974,765 ÷ 3 = 34,991,588.3333
If the quotient is a whole number, then 3 and 34,991,588.3333 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 | 104,974,765 | |
| -1 | -104,974,765 |
Let's try dividing by 4:
104,974,765 ÷ 4 = 26,243,691.25
If the quotient is a whole number, then 4 and 26,243,691.25 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 | 104,974,765 | |
| -1 | 104,974,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,487 | 2,017 | 7,435 | 10,085 | 10,409 | 14,119 | 52,045 | 70,595 | 2,999,279 | 14,996,395 | 20,994,953 | 104,974,765 |
| -1 | -5 | -7 | -35 | -1,487 | -2,017 | -7,435 | -10,085 | -10,409 | -14,119 | -52,045 | -70,595 | -2,999,279 | -14,996,395 | -20,994,953 | -104,974,765 |
