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 4,243,099, 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 | 4,243,099 | |
| -1 | -4,243,099 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,243,099.
Example:
1 x 4,243,099 = 4,243,099
and
-1 x -4,243,099 = 4,243,099
Notice both answers equal 4,243,099
With that explanation out of the way, let's continue. Next, we take the number 4,243,099 and divide it by 2:
4,243,099 ÷ 2 = 2,121,549.5
If the quotient is a whole number, then 2 and 2,121,549.5 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 | 4,243,099 | |
| -1 | -4,243,099 |
Now, we try dividing 4,243,099 by 3:
4,243,099 ÷ 3 = 1,414,366.3333
If the quotient is a whole number, then 3 and 1,414,366.3333 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 | 4,243,099 | |
| -1 | -4,243,099 |
Let's try dividing by 4:
4,243,099 ÷ 4 = 1,060,774.75
If the quotient is a whole number, then 4 and 1,060,774.75 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 | 4,243,099 | |
| -1 | 4,243,099 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 61 | 133 | 427 | 523 | 1,159 | 3,661 | 8,113 | 9,937 | 31,903 | 69,559 | 223,321 | 606,157 | 4,243,099 |
| -1 | -7 | -19 | -61 | -133 | -427 | -523 | -1,159 | -3,661 | -8,113 | -9,937 | -31,903 | -69,559 | -223,321 | -606,157 | -4,243,099 |
