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 340,034,443, 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 | 340,034,443 | |
| -1 | -340,034,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 340,034,443.
Example:
1 x 340,034,443 = 340,034,443
and
-1 x -340,034,443 = 340,034,443
Notice both answers equal 340,034,443
With that explanation out of the way, let's continue. Next, we take the number 340,034,443 and divide it by 2:
340,034,443 ÷ 2 = 170,017,221.5
If the quotient is a whole number, then 2 and 170,017,221.5 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 | 340,034,443 | |
| -1 | -340,034,443 |
Now, we try dividing 340,034,443 by 3:
340,034,443 ÷ 3 = 113,344,814.3333
If the quotient is a whole number, then 3 and 113,344,814.3333 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 | 340,034,443 | |
| -1 | -340,034,443 |
Let's try dividing by 4:
340,034,443 ÷ 4 = 85,008,610.75
If the quotient is a whole number, then 4 and 85,008,610.75 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 | 340,034,443 | |
| -1 | 340,034,443 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 41 | 217 | 287 | 1,271 | 8,897 | 38,219 | 267,533 | 1,184,789 | 1,566,979 | 8,293,523 | 10,968,853 | 48,576,349 | 340,034,443 |
| -1 | -7 | -31 | -41 | -217 | -287 | -1,271 | -8,897 | -38,219 | -267,533 | -1,184,789 | -1,566,979 | -8,293,523 | -10,968,853 | -48,576,349 | -340,034,443 |
