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 42,162,661, 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 | 42,162,661 | |
| -1 | -42,162,661 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,162,661.
Example:
1 x 42,162,661 = 42,162,661
and
-1 x -42,162,661 = 42,162,661
Notice both answers equal 42,162,661
With that explanation out of the way, let's continue. Next, we take the number 42,162,661 and divide it by 2:
42,162,661 ÷ 2 = 21,081,330.5
If the quotient is a whole number, then 2 and 21,081,330.5 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 | 42,162,661 | |
| -1 | -42,162,661 |
Now, we try dividing 42,162,661 by 3:
42,162,661 ÷ 3 = 14,054,220.3333
If the quotient is a whole number, then 3 and 14,054,220.3333 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 | 42,162,661 | |
| -1 | -42,162,661 |
Let's try dividing by 4:
42,162,661 ÷ 4 = 10,540,665.25
If the quotient is a whole number, then 4 and 10,540,665.25 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 | 42,162,661 | |
| -1 | 42,162,661 |
If you did it right, you will end up with this table:
| 1 | 43 | 491 | 1,997 | 21,113 | 85,871 | 980,527 | 42,162,661 |
| -1 | -43 | -491 | -1,997 | -21,113 | -85,871 | -980,527 | -42,162,661 |
