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 42,656,653, 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 | 42,656,653 | |
| -1 | -42,656,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,656,653.
Example:
1 x 42,656,653 = 42,656,653
and
-1 x -42,656,653 = 42,656,653
Notice both answers equal 42,656,653
With that explanation out of the way, let's continue. Next, we take the number 42,656,653 and divide it by 2:
42,656,653 ÷ 2 = 21,328,326.5
If the quotient is a whole number, then 2 and 21,328,326.5 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 | 42,656,653 | |
| -1 | -42,656,653 |
Now, we try dividing 42,656,653 by 3:
42,656,653 ÷ 3 = 14,218,884.3333
If the quotient is a whole number, then 3 and 14,218,884.3333 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 | 42,656,653 | |
| -1 | -42,656,653 |
Let's try dividing by 4:
42,656,653 ÷ 4 = 10,664,163.25
If the quotient is a whole number, then 4 and 10,664,163.25 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 | 42,656,653 | |
| -1 | 42,656,653 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 247 | 373 | 463 | 4,849 | 6,019 | 7,087 | 8,797 | 92,131 | 114,361 | 172,699 | 2,245,087 | 3,281,281 | 42,656,653 |
| -1 | -13 | -19 | -247 | -373 | -463 | -4,849 | -6,019 | -7,087 | -8,797 | -92,131 | -114,361 | -172,699 | -2,245,087 | -3,281,281 | -42,656,653 |
