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 68,847,229, 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 | 68,847,229 | |
| -1 | -68,847,229 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,847,229.
Example:
1 x 68,847,229 = 68,847,229
and
-1 x -68,847,229 = 68,847,229
Notice both answers equal 68,847,229
With that explanation out of the way, let's continue. Next, we take the number 68,847,229 and divide it by 2:
68,847,229 ÷ 2 = 34,423,614.5
If the quotient is a whole number, then 2 and 34,423,614.5 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 | 68,847,229 | |
| -1 | -68,847,229 |
Now, we try dividing 68,847,229 by 3:
68,847,229 ÷ 3 = 22,949,076.3333
If the quotient is a whole number, then 3 and 22,949,076.3333 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 | 68,847,229 | |
| -1 | -68,847,229 |
Let's try dividing by 4:
68,847,229 ÷ 4 = 17,211,807.25
If the quotient is a whole number, then 4 and 17,211,807.25 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 | 68,847,229 | |
| -1 | 68,847,229 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 347 | 1,061 | 3,817 | 5,899 | 11,671 | 18,037 | 64,889 | 198,407 | 368,167 | 4,049,837 | 6,258,839 | 68,847,229 |
| -1 | -11 | -17 | -187 | -347 | -1,061 | -3,817 | -5,899 | -11,671 | -18,037 | -64,889 | -198,407 | -368,167 | -4,049,837 | -6,258,839 | -68,847,229 |
