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 42,253,735, 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 | 42,253,735 | |
| -1 | -42,253,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,253,735.
Example:
1 x 42,253,735 = 42,253,735
and
-1 x -42,253,735 = 42,253,735
Notice both answers equal 42,253,735
With that explanation out of the way, let's continue. Next, we take the number 42,253,735 and divide it by 2:
42,253,735 ÷ 2 = 21,126,867.5
If the quotient is a whole number, then 2 and 21,126,867.5 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 | 42,253,735 | |
| -1 | -42,253,735 |
Now, we try dividing 42,253,735 by 3:
42,253,735 ÷ 3 = 14,084,578.3333
If the quotient is a whole number, then 3 and 14,084,578.3333 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 | 42,253,735 | |
| -1 | -42,253,735 |
Let's try dividing by 4:
42,253,735 ÷ 4 = 10,563,433.75
If the quotient is a whole number, then 4 and 10,563,433.75 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 | 42,253,735 | |
| -1 | 42,253,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 59 | 215 | 295 | 2,537 | 3,331 | 12,685 | 16,655 | 143,233 | 196,529 | 716,165 | 982,645 | 8,450,747 | 42,253,735 |
| -1 | -5 | -43 | -59 | -215 | -295 | -2,537 | -3,331 | -12,685 | -16,655 | -143,233 | -196,529 | -716,165 | -982,645 | -8,450,747 | -42,253,735 |
