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 42,284,291, 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 | 42,284,291 | |
| -1 | -42,284,291 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,284,291.
Example:
1 x 42,284,291 = 42,284,291
and
-1 x -42,284,291 = 42,284,291
Notice both answers equal 42,284,291
With that explanation out of the way, let's continue. Next, we take the number 42,284,291 and divide it by 2:
42,284,291 ÷ 2 = 21,142,145.5
If the quotient is a whole number, then 2 and 21,142,145.5 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 | 42,284,291 | |
| -1 | -42,284,291 |
Now, we try dividing 42,284,291 by 3:
42,284,291 ÷ 3 = 14,094,763.6667
If the quotient is a whole number, then 3 and 14,094,763.6667 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 | 42,284,291 | |
| -1 | -42,284,291 |
Let's try dividing by 4:
42,284,291 ÷ 4 = 10,571,072.75
If the quotient is a whole number, then 4 and 10,571,072.75 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 | 42,284,291 | |
| -1 | 42,284,291 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 29 | 133 | 203 | 361 | 551 | 577 | 2,527 | 3,857 | 4,039 | 10,469 | 10,963 | 16,733 | 73,283 | 76,741 | 117,131 | 208,297 | 317,927 | 1,458,079 | 2,225,489 | 6,040,613 | 42,284,291 |
| -1 | -7 | -19 | -29 | -133 | -203 | -361 | -551 | -577 | -2,527 | -3,857 | -4,039 | -10,469 | -10,963 | -16,733 | -73,283 | -76,741 | -117,131 | -208,297 | -317,927 | -1,458,079 | -2,225,489 | -6,040,613 | -42,284,291 |
