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 342,034,615, 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 | 342,034,615 | |
| -1 | -342,034,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 342,034,615.
Example:
1 x 342,034,615 = 342,034,615
and
-1 x -342,034,615 = 342,034,615
Notice both answers equal 342,034,615
With that explanation out of the way, let's continue. Next, we take the number 342,034,615 and divide it by 2:
342,034,615 ÷ 2 = 171,017,307.5
If the quotient is a whole number, then 2 and 171,017,307.5 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 | 342,034,615 | |
| -1 | -342,034,615 |
Now, we try dividing 342,034,615 by 3:
342,034,615 ÷ 3 = 114,011,538.3333
If the quotient is a whole number, then 3 and 114,011,538.3333 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 | 342,034,615 | |
| -1 | -342,034,615 |
Let's try dividing by 4:
342,034,615 ÷ 4 = 85,508,653.75
If the quotient is a whole number, then 4 and 85,508,653.75 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 | 342,034,615 | |
| -1 | 342,034,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 113 | 565 | 1,469 | 7,345 | 46,567 | 232,835 | 605,371 | 3,026,855 | 5,262,071 | 26,310,355 | 68,406,923 | 342,034,615 |
| -1 | -5 | -13 | -65 | -113 | -565 | -1,469 | -7,345 | -46,567 | -232,835 | -605,371 | -3,026,855 | -5,262,071 | -26,310,355 | -68,406,923 | -342,034,615 |
