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 42,214,039, 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 | 42,214,039 | |
| -1 | -42,214,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,214,039.
Example:
1 x 42,214,039 = 42,214,039
and
-1 x -42,214,039 = 42,214,039
Notice both answers equal 42,214,039
With that explanation out of the way, let's continue. Next, we take the number 42,214,039 and divide it by 2:
42,214,039 ÷ 2 = 21,107,019.5
If the quotient is a whole number, then 2 and 21,107,019.5 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 | 42,214,039 | |
| -1 | -42,214,039 |
Now, we try dividing 42,214,039 by 3:
42,214,039 ÷ 3 = 14,071,346.3333
If the quotient is a whole number, then 3 and 14,071,346.3333 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 | 42,214,039 | |
| -1 | -42,214,039 |
Let's try dividing by 4:
42,214,039 ÷ 4 = 10,553,509.75
If the quotient is a whole number, then 4 and 10,553,509.75 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 | 42,214,039 | |
| -1 | 42,214,039 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 49 | 161 | 343 | 1,127 | 5,351 | 7,889 | 37,457 | 123,073 | 262,199 | 861,511 | 1,835,393 | 6,030,577 | 42,214,039 |
| -1 | -7 | -23 | -49 | -161 | -343 | -1,127 | -5,351 | -7,889 | -37,457 | -123,073 | -262,199 | -861,511 | -1,835,393 | -6,030,577 | -42,214,039 |
