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 42,655,459, 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 | 42,655,459 | |
| -1 | -42,655,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,655,459.
Example:
1 x 42,655,459 = 42,655,459
and
-1 x -42,655,459 = 42,655,459
Notice both answers equal 42,655,459
With that explanation out of the way, let's continue. Next, we take the number 42,655,459 and divide it by 2:
42,655,459 ÷ 2 = 21,327,729.5
If the quotient is a whole number, then 2 and 21,327,729.5 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 | 42,655,459 | |
| -1 | -42,655,459 |
Now, we try dividing 42,655,459 by 3:
42,655,459 ÷ 3 = 14,218,486.3333
If the quotient is a whole number, then 3 and 14,218,486.3333 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 | 42,655,459 | |
| -1 | -42,655,459 |
Let's try dividing by 4:
42,655,459 ÷ 4 = 10,663,864.75
If the quotient is a whole number, then 4 and 10,663,864.75 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 | 42,655,459 | |
| -1 | 42,655,459 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 97 | 679 | 1,067 | 5,711 | 7,469 | 39,977 | 62,821 | 439,747 | 553,967 | 3,877,769 | 6,093,637 | 42,655,459 |
| -1 | -7 | -11 | -77 | -97 | -679 | -1,067 | -5,711 | -7,469 | -39,977 | -62,821 | -439,747 | -553,967 | -3,877,769 | -6,093,637 | -42,655,459 |
