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 426,556,403, 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 | 426,556,403 | |
| -1 | -426,556,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 426,556,403.
Example:
1 x 426,556,403 = 426,556,403
and
-1 x -426,556,403 = 426,556,403
Notice both answers equal 426,556,403
With that explanation out of the way, let's continue. Next, we take the number 426,556,403 and divide it by 2:
426,556,403 ÷ 2 = 213,278,201.5
If the quotient is a whole number, then 2 and 213,278,201.5 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 | 426,556,403 | |
| -1 | -426,556,403 |
Now, we try dividing 426,556,403 by 3:
426,556,403 ÷ 3 = 142,185,467.6667
If the quotient is a whole number, then 3 and 142,185,467.6667 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 | 426,556,403 | |
| -1 | -426,556,403 |
Let's try dividing by 4:
426,556,403 ÷ 4 = 106,639,100.75
If the quotient is a whole number, then 4 and 106,639,100.75 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 | 426,556,403 | |
| -1 | 426,556,403 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 91 | 133 | 247 | 1,729 | 246,707 | 1,726,949 | 3,207,191 | 4,687,433 | 22,450,337 | 32,812,031 | 60,936,629 | 426,556,403 |
| -1 | -7 | -13 | -19 | -91 | -133 | -247 | -1,729 | -246,707 | -1,726,949 | -3,207,191 | -4,687,433 | -22,450,337 | -32,812,031 | -60,936,629 | -426,556,403 |
