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 4,048,355, 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 | 4,048,355 | |
| -1 | -4,048,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,048,355.
Example:
1 x 4,048,355 = 4,048,355
and
-1 x -4,048,355 = 4,048,355
Notice both answers equal 4,048,355
With that explanation out of the way, let's continue. Next, we take the number 4,048,355 and divide it by 2:
4,048,355 ÷ 2 = 2,024,177.5
If the quotient is a whole number, then 2 and 2,024,177.5 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 | 4,048,355 | |
| -1 | -4,048,355 |
Now, we try dividing 4,048,355 by 3:
4,048,355 ÷ 3 = 1,349,451.6667
If the quotient is a whole number, then 3 and 1,349,451.6667 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 | 4,048,355 | |
| -1 | -4,048,355 |
Let's try dividing by 4:
4,048,355 ÷ 4 = 1,012,088.75
If the quotient is a whole number, then 4 and 1,012,088.75 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 | 4,048,355 | |
| -1 | 4,048,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 79 | 185 | 277 | 395 | 1,385 | 2,923 | 10,249 | 14,615 | 21,883 | 51,245 | 109,415 | 809,671 | 4,048,355 |
| -1 | -5 | -37 | -79 | -185 | -277 | -395 | -1,385 | -2,923 | -10,249 | -14,615 | -21,883 | -51,245 | -109,415 | -809,671 | -4,048,355 |
