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 42,824,431, 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 | 42,824,431 | |
| -1 | -42,824,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,824,431.
Example:
1 x 42,824,431 = 42,824,431
and
-1 x -42,824,431 = 42,824,431
Notice both answers equal 42,824,431
With that explanation out of the way, let's continue. Next, we take the number 42,824,431 and divide it by 2:
42,824,431 ÷ 2 = 21,412,215.5
If the quotient is a whole number, then 2 and 21,412,215.5 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 | 42,824,431 | |
| -1 | -42,824,431 |
Now, we try dividing 42,824,431 by 3:
42,824,431 ÷ 3 = 14,274,810.3333
If the quotient is a whole number, then 3 and 14,274,810.3333 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 | 42,824,431 | |
| -1 | -42,824,431 |
Let's try dividing by 4:
42,824,431 ÷ 4 = 10,706,107.75
If the quotient is a whole number, then 4 and 10,706,107.75 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 | 42,824,431 | |
| -1 | 42,824,431 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 71 | 83 | 169 | 559 | 923 | 1,079 | 3,053 | 3,569 | 5,893 | 7,267 | 11,999 | 14,027 | 39,689 | 46,397 | 76,609 | 253,399 | 515,957 | 603,161 | 995,917 | 3,294,187 | 42,824,431 |
| -1 | -13 | -43 | -71 | -83 | -169 | -559 | -923 | -1,079 | -3,053 | -3,569 | -5,893 | -7,267 | -11,999 | -14,027 | -39,689 | -46,397 | -76,609 | -253,399 | -515,957 | -603,161 | -995,917 | -3,294,187 | -42,824,431 |
