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 68,828,795, 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 | 68,828,795 | |
| -1 | -68,828,795 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,828,795.
Example:
1 x 68,828,795 = 68,828,795
and
-1 x -68,828,795 = 68,828,795
Notice both answers equal 68,828,795
With that explanation out of the way, let's continue. Next, we take the number 68,828,795 and divide it by 2:
68,828,795 ÷ 2 = 34,414,397.5
If the quotient is a whole number, then 2 and 34,414,397.5 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 | 68,828,795 | |
| -1 | -68,828,795 |
Now, we try dividing 68,828,795 by 3:
68,828,795 ÷ 3 = 22,942,931.6667
If the quotient is a whole number, then 3 and 22,942,931.6667 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 | 68,828,795 | |
| -1 | -68,828,795 |
Let's try dividing by 4:
68,828,795 ÷ 4 = 17,207,198.75
If the quotient is a whole number, then 4 and 17,207,198.75 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 | 68,828,795 | |
| -1 | 68,828,795 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 467 | 2,335 | 3,269 | 4,211 | 16,345 | 21,055 | 29,477 | 147,385 | 1,966,537 | 9,832,685 | 13,765,759 | 68,828,795 |
| -1 | -5 | -7 | -35 | -467 | -2,335 | -3,269 | -4,211 | -16,345 | -21,055 | -29,477 | -147,385 | -1,966,537 | -9,832,685 | -13,765,759 | -68,828,795 |
