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 246,042,343, 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 | 246,042,343 | |
| -1 | -246,042,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 246,042,343.
Example:
1 x 246,042,343 = 246,042,343
and
-1 x -246,042,343 = 246,042,343
Notice both answers equal 246,042,343
With that explanation out of the way, let's continue. Next, we take the number 246,042,343 and divide it by 2:
246,042,343 ÷ 2 = 123,021,171.5
If the quotient is a whole number, then 2 and 123,021,171.5 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 | 246,042,343 | |
| -1 | -246,042,343 |
Now, we try dividing 246,042,343 by 3:
246,042,343 ÷ 3 = 82,014,114.3333
If the quotient is a whole number, then 3 and 82,014,114.3333 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 | 246,042,343 | |
| -1 | -246,042,343 |
Let's try dividing by 4:
246,042,343 ÷ 4 = 61,510,585.75
If the quotient is a whole number, then 4 and 61,510,585.75 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 | 246,042,343 | |
| -1 | 246,042,343 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 97 | 323 | 1,649 | 1,843 | 7,853 | 31,331 | 133,501 | 149,207 | 761,741 | 2,536,519 | 12,949,597 | 14,473,079 | 246,042,343 |
| -1 | -17 | -19 | -97 | -323 | -1,649 | -1,843 | -7,853 | -31,331 | -133,501 | -149,207 | -761,741 | -2,536,519 | -12,949,597 | -14,473,079 | -246,042,343 |
