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 345,337,765, 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 | 345,337,765 | |
| -1 | -345,337,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 345,337,765.
Example:
1 x 345,337,765 = 345,337,765
and
-1 x -345,337,765 = 345,337,765
Notice both answers equal 345,337,765
With that explanation out of the way, let's continue. Next, we take the number 345,337,765 and divide it by 2:
345,337,765 ÷ 2 = 172,668,882.5
If the quotient is a whole number, then 2 and 172,668,882.5 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 | 345,337,765 | |
| -1 | -345,337,765 |
Now, we try dividing 345,337,765 by 3:
345,337,765 ÷ 3 = 115,112,588.3333
If the quotient is a whole number, then 3 and 115,112,588.3333 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 | 345,337,765 | |
| -1 | -345,337,765 |
Let's try dividing by 4:
345,337,765 ÷ 4 = 86,334,441.25
If the quotient is a whole number, then 4 and 86,334,441.25 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 | 345,337,765 | |
| -1 | 345,337,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 127 | 335 | 635 | 8,117 | 8,509 | 40,585 | 42,545 | 543,839 | 1,030,859 | 2,719,195 | 5,154,295 | 69,067,553 | 345,337,765 |
| -1 | -5 | -67 | -127 | -335 | -635 | -8,117 | -8,509 | -40,585 | -42,545 | -543,839 | -1,030,859 | -2,719,195 | -5,154,295 | -69,067,553 | -345,337,765 |
