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 33,518,905, 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 | 33,518,905 | |
| -1 | -33,518,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,518,905.
Example:
1 x 33,518,905 = 33,518,905
and
-1 x -33,518,905 = 33,518,905
Notice both answers equal 33,518,905
With that explanation out of the way, let's continue. Next, we take the number 33,518,905 and divide it by 2:
33,518,905 ÷ 2 = 16,759,452.5
If the quotient is a whole number, then 2 and 16,759,452.5 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 | 33,518,905 | |
| -1 | -33,518,905 |
Now, we try dividing 33,518,905 by 3:
33,518,905 ÷ 3 = 11,172,968.3333
If the quotient is a whole number, then 3 and 11,172,968.3333 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 | 33,518,905 | |
| -1 | -33,518,905 |
Let's try dividing by 4:
33,518,905 ÷ 4 = 8,379,726.25
If the quotient is a whole number, then 4 and 8,379,726.25 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 | 33,518,905 | |
| -1 | 33,518,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 30,893 | 154,465 | 216,251 | 957,683 | 1,081,255 | 4,788,415 | 6,703,781 | 33,518,905 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -30,893 | -154,465 | -216,251 | -957,683 | -1,081,255 | -4,788,415 | -6,703,781 | -33,518,905 |
