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 42,031,429, 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 | 42,031,429 | |
| -1 | -42,031,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,031,429.
Example:
1 x 42,031,429 = 42,031,429
and
-1 x -42,031,429 = 42,031,429
Notice both answers equal 42,031,429
With that explanation out of the way, let's continue. Next, we take the number 42,031,429 and divide it by 2:
42,031,429 ÷ 2 = 21,015,714.5
If the quotient is a whole number, then 2 and 21,015,714.5 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 | 42,031,429 | |
| -1 | -42,031,429 |
Now, we try dividing 42,031,429 by 3:
42,031,429 ÷ 3 = 14,010,476.3333
If the quotient is a whole number, then 3 and 14,010,476.3333 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 | 42,031,429 | |
| -1 | -42,031,429 |
Let's try dividing by 4:
42,031,429 ÷ 4 = 10,507,857.25
If the quotient is a whole number, then 4 and 10,507,857.25 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 | 42,031,429 | |
| -1 | 42,031,429 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 73 | 187 | 803 | 1,241 | 3,079 | 13,651 | 33,869 | 52,343 | 224,767 | 575,773 | 2,472,437 | 3,821,039 | 42,031,429 |
| -1 | -11 | -17 | -73 | -187 | -803 | -1,241 | -3,079 | -13,651 | -33,869 | -52,343 | -224,767 | -575,773 | -2,472,437 | -3,821,039 | -42,031,429 |
