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 103,400,401, 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 | 103,400,401 | |
| -1 | -103,400,401 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,400,401.
Example:
1 x 103,400,401 = 103,400,401
and
-1 x -103,400,401 = 103,400,401
Notice both answers equal 103,400,401
With that explanation out of the way, let's continue. Next, we take the number 103,400,401 and divide it by 2:
103,400,401 ÷ 2 = 51,700,200.5
If the quotient is a whole number, then 2 and 51,700,200.5 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 | 103,400,401 | |
| -1 | -103,400,401 |
Now, we try dividing 103,400,401 by 3:
103,400,401 ÷ 3 = 34,466,800.3333
If the quotient is a whole number, then 3 and 34,466,800.3333 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 | 103,400,401 | |
| -1 | -103,400,401 |
Let's try dividing by 4:
103,400,401 ÷ 4 = 25,850,100.25
If the quotient is a whole number, then 4 and 25,850,100.25 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 | 103,400,401 | |
| -1 | 103,400,401 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 419 | 463 | 533 | 5,447 | 6,019 | 17,179 | 18,983 | 193,997 | 223,327 | 246,779 | 2,521,961 | 7,953,877 | 103,400,401 |
| -1 | -13 | -41 | -419 | -463 | -533 | -5,447 | -6,019 | -17,179 | -18,983 | -193,997 | -223,327 | -246,779 | -2,521,961 | -7,953,877 | -103,400,401 |
