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 346,062,871, 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 | 346,062,871 | |
| -1 | -346,062,871 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 346,062,871.
Example:
1 x 346,062,871 = 346,062,871
and
-1 x -346,062,871 = 346,062,871
Notice both answers equal 346,062,871
With that explanation out of the way, let's continue. Next, we take the number 346,062,871 and divide it by 2:
346,062,871 ÷ 2 = 173,031,435.5
If the quotient is a whole number, then 2 and 173,031,435.5 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 | 346,062,871 | |
| -1 | -346,062,871 |
Now, we try dividing 346,062,871 by 3:
346,062,871 ÷ 3 = 115,354,290.3333
If the quotient is a whole number, then 3 and 115,354,290.3333 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 | 346,062,871 | |
| -1 | -346,062,871 |
Let's try dividing by 4:
346,062,871 ÷ 4 = 86,515,717.75
If the quotient is a whole number, then 4 and 86,515,717.75 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 | 346,062,871 | |
| -1 | 346,062,871 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 283 | 1,981 | 3,113 | 15,881 | 21,791 | 111,167 | 174,691 | 1,222,837 | 4,494,323 | 31,460,261 | 49,437,553 | 346,062,871 |
| -1 | -7 | -11 | -77 | -283 | -1,981 | -3,113 | -15,881 | -21,791 | -111,167 | -174,691 | -1,222,837 | -4,494,323 | -31,460,261 | -49,437,553 | -346,062,871 |
