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 4,257,235, 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 | 4,257,235 | |
| -1 | -4,257,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,257,235.
Example:
1 x 4,257,235 = 4,257,235
and
-1 x -4,257,235 = 4,257,235
Notice both answers equal 4,257,235
With that explanation out of the way, let's continue. Next, we take the number 4,257,235 and divide it by 2:
4,257,235 ÷ 2 = 2,128,617.5
If the quotient is a whole number, then 2 and 2,128,617.5 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 | 4,257,235 | |
| -1 | -4,257,235 |
Now, we try dividing 4,257,235 by 3:
4,257,235 ÷ 3 = 1,419,078.3333
If the quotient is a whole number, then 3 and 1,419,078.3333 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 | 4,257,235 | |
| -1 | -4,257,235 |
Let's try dividing by 4:
4,257,235 ÷ 4 = 1,064,308.75
If the quotient is a whole number, then 4 and 1,064,308.75 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 | 4,257,235 | |
| -1 | 4,257,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 41 | 95 | 205 | 779 | 1,093 | 3,895 | 5,465 | 20,767 | 44,813 | 103,835 | 224,065 | 851,447 | 4,257,235 |
| -1 | -5 | -19 | -41 | -95 | -205 | -779 | -1,093 | -3,895 | -5,465 | -20,767 | -44,813 | -103,835 | -224,065 | -851,447 | -4,257,235 |
