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 104,210,401, 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 | 104,210,401 | |
| -1 | -104,210,401 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,210,401.
Example:
1 x 104,210,401 = 104,210,401
and
-1 x -104,210,401 = 104,210,401
Notice both answers equal 104,210,401
With that explanation out of the way, let's continue. Next, we take the number 104,210,401 and divide it by 2:
104,210,401 ÷ 2 = 52,105,200.5
If the quotient is a whole number, then 2 and 52,105,200.5 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 | 104,210,401 | |
| -1 | -104,210,401 |
Now, we try dividing 104,210,401 by 3:
104,210,401 ÷ 3 = 34,736,800.3333
If the quotient is a whole number, then 3 and 34,736,800.3333 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 | 104,210,401 | |
| -1 | -104,210,401 |
Let's try dividing by 4:
104,210,401 ÷ 4 = 26,052,600.25
If the quotient is a whole number, then 4 and 26,052,600.25 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 | 104,210,401 | |
| -1 | 104,210,401 |
If you did it right, you will end up with this table:
| 1 | 23 | 79 | 83 | 691 | 1,817 | 1,909 | 6,557 | 15,893 | 54,589 | 57,353 | 150,811 | 1,255,547 | 1,319,119 | 4,530,887 | 104,210,401 |
| -1 | -23 | -79 | -83 | -691 | -1,817 | -1,909 | -6,557 | -15,893 | -54,589 | -57,353 | -150,811 | -1,255,547 | -1,319,119 | -4,530,887 | -104,210,401 |
