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 42,046,433, 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 | 42,046,433 | |
| -1 | -42,046,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,046,433.
Example:
1 x 42,046,433 = 42,046,433
and
-1 x -42,046,433 = 42,046,433
Notice both answers equal 42,046,433
With that explanation out of the way, let's continue. Next, we take the number 42,046,433 and divide it by 2:
42,046,433 ÷ 2 = 21,023,216.5
If the quotient is a whole number, then 2 and 21,023,216.5 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 | 42,046,433 | |
| -1 | -42,046,433 |
Now, we try dividing 42,046,433 by 3:
42,046,433 ÷ 3 = 14,015,477.6667
If the quotient is a whole number, then 3 and 14,015,477.6667 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 | 42,046,433 | |
| -1 | -42,046,433 |
Let's try dividing by 4:
42,046,433 ÷ 4 = 10,511,608.25
If the quotient is a whole number, then 4 and 10,511,608.25 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 | 42,046,433 | |
| -1 | 42,046,433 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 29 | 143 | 319 | 377 | 4,147 | 10,139 | 111,529 | 131,807 | 294,031 | 1,449,877 | 3,234,341 | 3,822,403 | 42,046,433 |
| -1 | -11 | -13 | -29 | -143 | -319 | -377 | -4,147 | -10,139 | -111,529 | -131,807 | -294,031 | -1,449,877 | -3,234,341 | -3,822,403 | -42,046,433 |
