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 345,475,403, 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 | 345,475,403 | |
| -1 | -345,475,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 345,475,403.
Example:
1 x 345,475,403 = 345,475,403
and
-1 x -345,475,403 = 345,475,403
Notice both answers equal 345,475,403
With that explanation out of the way, let's continue. Next, we take the number 345,475,403 and divide it by 2:
345,475,403 ÷ 2 = 172,737,701.5
If the quotient is a whole number, then 2 and 172,737,701.5 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 | 345,475,403 | |
| -1 | -345,475,403 |
Now, we try dividing 345,475,403 by 3:
345,475,403 ÷ 3 = 115,158,467.6667
If the quotient is a whole number, then 3 and 115,158,467.6667 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 | 345,475,403 | |
| -1 | -345,475,403 |
Let's try dividing by 4:
345,475,403 ÷ 4 = 86,368,850.75
If the quotient is a whole number, then 4 and 86,368,850.75 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 | 345,475,403 | |
| -1 | 345,475,403 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 163 | 1,141 | 2,119 | 14,833 | 23,291 | 163,037 | 302,783 | 2,119,481 | 3,796,433 | 26,575,031 | 49,353,629 | 345,475,403 |
| -1 | -7 | -13 | -91 | -163 | -1,141 | -2,119 | -14,833 | -23,291 | -163,037 | -302,783 | -2,119,481 | -3,796,433 | -26,575,031 | -49,353,629 | -345,475,403 |
