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 68,671,043, 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 | 68,671,043 | |
| -1 | -68,671,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,671,043.
Example:
1 x 68,671,043 = 68,671,043
and
-1 x -68,671,043 = 68,671,043
Notice both answers equal 68,671,043
With that explanation out of the way, let's continue. Next, we take the number 68,671,043 and divide it by 2:
68,671,043 ÷ 2 = 34,335,521.5
If the quotient is a whole number, then 2 and 34,335,521.5 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 | 68,671,043 | |
| -1 | -68,671,043 |
Now, we try dividing 68,671,043 by 3:
68,671,043 ÷ 3 = 22,890,347.6667
If the quotient is a whole number, then 3 and 22,890,347.6667 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 | 68,671,043 | |
| -1 | -68,671,043 |
Let's try dividing by 4:
68,671,043 ÷ 4 = 17,167,760.75
If the quotient is a whole number, then 4 and 17,167,760.75 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 | 68,671,043 | |
| -1 | 68,671,043 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 43 | 203 | 301 | 1,247 | 7,867 | 8,729 | 55,069 | 228,143 | 338,281 | 1,597,001 | 2,367,967 | 9,810,149 | 68,671,043 |
| -1 | -7 | -29 | -43 | -203 | -301 | -1,247 | -7,867 | -8,729 | -55,069 | -228,143 | -338,281 | -1,597,001 | -2,367,967 | -9,810,149 | -68,671,043 |
