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 4,074,917, 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 | 4,074,917 | |
| -1 | -4,074,917 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,074,917.
Example:
1 x 4,074,917 = 4,074,917
and
-1 x -4,074,917 = 4,074,917
Notice both answers equal 4,074,917
With that explanation out of the way, let's continue. Next, we take the number 4,074,917 and divide it by 2:
4,074,917 ÷ 2 = 2,037,458.5
If the quotient is a whole number, then 2 and 2,037,458.5 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 | 4,074,917 | |
| -1 | -4,074,917 |
Now, we try dividing 4,074,917 by 3:
4,074,917 ÷ 3 = 1,358,305.6667
If the quotient is a whole number, then 3 and 1,358,305.6667 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 | 4,074,917 | |
| -1 | -4,074,917 |
Let's try dividing by 4:
4,074,917 ÷ 4 = 1,018,729.25
If the quotient is a whole number, then 4 and 1,018,729.25 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 | 4,074,917 | |
| -1 | 4,074,917 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 121 | 187 | 283 | 847 | 1,309 | 1,981 | 2,057 | 3,113 | 4,811 | 14,399 | 21,791 | 33,677 | 34,243 | 52,921 | 239,701 | 370,447 | 582,131 | 4,074,917 |
| -1 | -7 | -11 | -17 | -77 | -119 | -121 | -187 | -283 | -847 | -1,309 | -1,981 | -2,057 | -3,113 | -4,811 | -14,399 | -21,791 | -33,677 | -34,243 | -52,921 | -239,701 | -370,447 | -582,131 | -4,074,917 |
