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 4,716,415, 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 | 4,716,415 | |
| -1 | -4,716,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,716,415.
Example:
1 x 4,716,415 = 4,716,415
and
-1 x -4,716,415 = 4,716,415
Notice both answers equal 4,716,415
With that explanation out of the way, let's continue. Next, we take the number 4,716,415 and divide it by 2:
4,716,415 ÷ 2 = 2,358,207.5
If the quotient is a whole number, then 2 and 2,358,207.5 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 | 4,716,415 | |
| -1 | -4,716,415 |
Now, we try dividing 4,716,415 by 3:
4,716,415 ÷ 3 = 1,572,138.3333
If the quotient is a whole number, then 3 and 1,572,138.3333 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 | 4,716,415 | |
| -1 | -4,716,415 |
Let's try dividing by 4:
4,716,415 ÷ 4 = 1,179,103.75
If the quotient is a whole number, then 4 and 1,179,103.75 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 | 4,716,415 | |
| -1 | 4,716,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 2,957 | 14,785 | 32,527 | 85,753 | 162,635 | 428,765 | 943,283 | 4,716,415 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -2,957 | -14,785 | -32,527 | -85,753 | -162,635 | -428,765 | -943,283 | -4,716,415 |
