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 35,533,145, 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 | 35,533,145 | |
| -1 | -35,533,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,533,145.
Example:
1 x 35,533,145 = 35,533,145
and
-1 x -35,533,145 = 35,533,145
Notice both answers equal 35,533,145
With that explanation out of the way, let's continue. Next, we take the number 35,533,145 and divide it by 2:
35,533,145 ÷ 2 = 17,766,572.5
If the quotient is a whole number, then 2 and 17,766,572.5 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 | 35,533,145 | |
| -1 | -35,533,145 |
Now, we try dividing 35,533,145 by 3:
35,533,145 ÷ 3 = 11,844,381.6667
If the quotient is a whole number, then 3 and 11,844,381.6667 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 | 35,533,145 | |
| -1 | -35,533,145 |
Let's try dividing by 4:
35,533,145 ÷ 4 = 8,883,286.25
If the quotient is a whole number, then 4 and 8,883,286.25 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 | 35,533,145 | |
| -1 | 35,533,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 379 | 1,103 | 1,895 | 5,515 | 6,443 | 18,751 | 32,215 | 93,755 | 418,037 | 2,090,185 | 7,106,629 | 35,533,145 |
| -1 | -5 | -17 | -85 | -379 | -1,103 | -1,895 | -5,515 | -6,443 | -18,751 | -32,215 | -93,755 | -418,037 | -2,090,185 | -7,106,629 | -35,533,145 |
