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 103,533,433, 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 | 103,533,433 | |
| -1 | -103,533,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,533,433.
Example:
1 x 103,533,433 = 103,533,433
and
-1 x -103,533,433 = 103,533,433
Notice both answers equal 103,533,433
With that explanation out of the way, let's continue. Next, we take the number 103,533,433 and divide it by 2:
103,533,433 ÷ 2 = 51,766,716.5
If the quotient is a whole number, then 2 and 51,766,716.5 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 | 103,533,433 | |
| -1 | -103,533,433 |
Now, we try dividing 103,533,433 by 3:
103,533,433 ÷ 3 = 34,511,144.3333
If the quotient is a whole number, then 3 and 34,511,144.3333 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 | 103,533,433 | |
| -1 | -103,533,433 |
Let's try dividing by 4:
103,533,433 ÷ 4 = 25,883,358.25
If the quotient is a whole number, then 4 and 25,883,358.25 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 | 103,533,433 | |
| -1 | 103,533,433 |
If you did it right, you will end up with this table:
| 1 | 47 | 53 | 89 | 467 | 2,491 | 4,183 | 4,717 | 21,949 | 24,751 | 41,563 | 221,699 | 1,163,297 | 1,953,461 | 2,202,839 | 103,533,433 |
| -1 | -47 | -53 | -89 | -467 | -2,491 | -4,183 | -4,717 | -21,949 | -24,751 | -41,563 | -221,699 | -1,163,297 | -1,953,461 | -2,202,839 | -103,533,433 |
