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 66,336,335, 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 | 66,336,335 | |
| -1 | -66,336,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,336,335.
Example:
1 x 66,336,335 = 66,336,335
and
-1 x -66,336,335 = 66,336,335
Notice both answers equal 66,336,335
With that explanation out of the way, let's continue. Next, we take the number 66,336,335 and divide it by 2:
66,336,335 ÷ 2 = 33,168,167.5
If the quotient is a whole number, then 2 and 33,168,167.5 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 | 66,336,335 | |
| -1 | -66,336,335 |
Now, we try dividing 66,336,335 by 3:
66,336,335 ÷ 3 = 22,112,111.6667
If the quotient is a whole number, then 3 and 22,112,111.6667 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 | 66,336,335 | |
| -1 | -66,336,335 |
Let's try dividing by 4:
66,336,335 ÷ 4 = 16,584,083.75
If the quotient is a whole number, then 4 and 16,584,083.75 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 | 66,336,335 | |
| -1 | 66,336,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 739 | 1,381 | 3,695 | 6,905 | 9,607 | 17,953 | 48,035 | 89,765 | 1,020,559 | 5,102,795 | 13,267,267 | 66,336,335 |
| -1 | -5 | -13 | -65 | -739 | -1,381 | -3,695 | -6,905 | -9,607 | -17,953 | -48,035 | -89,765 | -1,020,559 | -5,102,795 | -13,267,267 | -66,336,335 |
