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 130,226,477, 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 | 130,226,477 | |
| -1 | -130,226,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,226,477.
Example:
1 x 130,226,477 = 130,226,477
and
-1 x -130,226,477 = 130,226,477
Notice both answers equal 130,226,477
With that explanation out of the way, let's continue. Next, we take the number 130,226,477 and divide it by 2:
130,226,477 ÷ 2 = 65,113,238.5
If the quotient is a whole number, then 2 and 65,113,238.5 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 | 130,226,477 | |
| -1 | -130,226,477 |
Now, we try dividing 130,226,477 by 3:
130,226,477 ÷ 3 = 43,408,825.6667
If the quotient is a whole number, then 3 and 43,408,825.6667 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 | 130,226,477 | |
| -1 | -130,226,477 |
Let's try dividing by 4:
130,226,477 ÷ 4 = 32,556,619.25
If the quotient is a whole number, then 4 and 32,556,619.25 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 | 130,226,477 | |
| -1 | 130,226,477 |
If you did it right, you will end up with this table:
| 1 | 17 | 97 | 151 | 523 | 1,649 | 2,567 | 8,891 | 14,647 | 50,731 | 78,973 | 248,999 | 862,427 | 1,342,541 | 7,660,381 | 130,226,477 |
| -1 | -17 | -97 | -151 | -523 | -1,649 | -2,567 | -8,891 | -14,647 | -50,731 | -78,973 | -248,999 | -862,427 | -1,342,541 | -7,660,381 | -130,226,477 |
