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 4,151,845, 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 | 4,151,845 | |
| -1 | -4,151,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,151,845.
Example:
1 x 4,151,845 = 4,151,845
and
-1 x -4,151,845 = 4,151,845
Notice both answers equal 4,151,845
With that explanation out of the way, let's continue. Next, we take the number 4,151,845 and divide it by 2:
4,151,845 ÷ 2 = 2,075,922.5
If the quotient is a whole number, then 2 and 2,075,922.5 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 | 4,151,845 | |
| -1 | -4,151,845 |
Now, we try dividing 4,151,845 by 3:
4,151,845 ÷ 3 = 1,383,948.3333
If the quotient is a whole number, then 3 and 1,383,948.3333 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 | 4,151,845 | |
| -1 | -4,151,845 |
Let's try dividing by 4:
4,151,845 ÷ 4 = 1,037,961.25
If the quotient is a whole number, then 4 and 1,037,961.25 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 | 4,151,845 | |
| -1 | 4,151,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 79 | 115 | 395 | 457 | 1,817 | 2,285 | 9,085 | 10,511 | 36,103 | 52,555 | 180,515 | 830,369 | 4,151,845 |
| -1 | -5 | -23 | -79 | -115 | -395 | -457 | -1,817 | -2,285 | -9,085 | -10,511 | -36,103 | -52,555 | -180,515 | -830,369 | -4,151,845 |
