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 68,426,035, 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 | 68,426,035 | |
| -1 | -68,426,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,426,035.
Example:
1 x 68,426,035 = 68,426,035
and
-1 x -68,426,035 = 68,426,035
Notice both answers equal 68,426,035
With that explanation out of the way, let's continue. Next, we take the number 68,426,035 and divide it by 2:
68,426,035 ÷ 2 = 34,213,017.5
If the quotient is a whole number, then 2 and 34,213,017.5 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 | 68,426,035 | |
| -1 | -68,426,035 |
Now, we try dividing 68,426,035 by 3:
68,426,035 ÷ 3 = 22,808,678.3333
If the quotient is a whole number, then 3 and 22,808,678.3333 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 | 68,426,035 | |
| -1 | -68,426,035 |
Let's try dividing by 4:
68,426,035 ÷ 4 = 17,106,508.75
If the quotient is a whole number, then 4 and 17,106,508.75 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 | 68,426,035 | |
| -1 | 68,426,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 317 | 1,585 | 1,877 | 7,291 | 9,385 | 36,455 | 43,171 | 215,855 | 595,009 | 2,975,045 | 13,685,207 | 68,426,035 |
| -1 | -5 | -23 | -115 | -317 | -1,585 | -1,877 | -7,291 | -9,385 | -36,455 | -43,171 | -215,855 | -595,009 | -2,975,045 | -13,685,207 | -68,426,035 |
