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 4,153,915, 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 | 4,153,915 | |
| -1 | -4,153,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,153,915.
Example:
1 x 4,153,915 = 4,153,915
and
-1 x -4,153,915 = 4,153,915
Notice both answers equal 4,153,915
With that explanation out of the way, let's continue. Next, we take the number 4,153,915 and divide it by 2:
4,153,915 ÷ 2 = 2,076,957.5
If the quotient is a whole number, then 2 and 2,076,957.5 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 | 4,153,915 | |
| -1 | -4,153,915 |
Now, we try dividing 4,153,915 by 3:
4,153,915 ÷ 3 = 1,384,638.3333
If the quotient is a whole number, then 3 and 1,384,638.3333 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 | 4,153,915 | |
| -1 | -4,153,915 |
Let's try dividing by 4:
4,153,915 ÷ 4 = 1,038,478.75
If the quotient is a whole number, then 4 and 1,038,478.75 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 | 4,153,915 | |
| -1 | 4,153,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 41 | 115 | 205 | 881 | 943 | 4,405 | 4,715 | 20,263 | 36,121 | 101,315 | 180,605 | 830,783 | 4,153,915 |
| -1 | -5 | -23 | -41 | -115 | -205 | -881 | -943 | -4,405 | -4,715 | -20,263 | -36,121 | -101,315 | -180,605 | -830,783 | -4,153,915 |
