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 68,292,635, 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 | 68,292,635 | |
| -1 | -68,292,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,292,635.
Example:
1 x 68,292,635 = 68,292,635
and
-1 x -68,292,635 = 68,292,635
Notice both answers equal 68,292,635
With that explanation out of the way, let's continue. Next, we take the number 68,292,635 and divide it by 2:
68,292,635 ÷ 2 = 34,146,317.5
If the quotient is a whole number, then 2 and 34,146,317.5 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 | 68,292,635 | |
| -1 | -68,292,635 |
Now, we try dividing 68,292,635 by 3:
68,292,635 ÷ 3 = 22,764,211.6667
If the quotient is a whole number, then 3 and 22,764,211.6667 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 | 68,292,635 | |
| -1 | -68,292,635 |
Let's try dividing by 4:
68,292,635 ÷ 4 = 17,073,158.75
If the quotient is a whole number, then 4 and 17,073,158.75 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 | 68,292,635 | |
| -1 | 68,292,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 223 | 1,115 | 2,663 | 5,129 | 13,315 | 25,645 | 61,249 | 306,245 | 593,849 | 2,969,245 | 13,658,527 | 68,292,635 |
| -1 | -5 | -23 | -115 | -223 | -1,115 | -2,663 | -5,129 | -13,315 | -25,645 | -61,249 | -306,245 | -593,849 | -2,969,245 | -13,658,527 | -68,292,635 |
