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 345,504,367, 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 | 345,504,367 | |
| -1 | -345,504,367 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 345,504,367.
Example:
1 x 345,504,367 = 345,504,367
and
-1 x -345,504,367 = 345,504,367
Notice both answers equal 345,504,367
With that explanation out of the way, let's continue. Next, we take the number 345,504,367 and divide it by 2:
345,504,367 ÷ 2 = 172,752,183.5
If the quotient is a whole number, then 2 and 172,752,183.5 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 | 345,504,367 | |
| -1 | -345,504,367 |
Now, we try dividing 345,504,367 by 3:
345,504,367 ÷ 3 = 115,168,122.3333
If the quotient is a whole number, then 3 and 115,168,122.3333 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 | 345,504,367 | |
| -1 | -345,504,367 |
Let's try dividing by 4:
345,504,367 ÷ 4 = 86,376,091.75
If the quotient is a whole number, then 4 and 86,376,091.75 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 | 345,504,367 | |
| -1 | 345,504,367 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 79 | 299 | 1,027 | 1,817 | 14,627 | 23,621 | 190,151 | 336,421 | 1,155,533 | 4,373,473 | 15,021,929 | 26,577,259 | 345,504,367 |
| -1 | -13 | -23 | -79 | -299 | -1,027 | -1,817 | -14,627 | -23,621 | -190,151 | -336,421 | -1,155,533 | -4,373,473 | -15,021,929 | -26,577,259 | -345,504,367 |
