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 4,472,815, 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 | 4,472,815 | |
| -1 | -4,472,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,472,815.
Example:
1 x 4,472,815 = 4,472,815
and
-1 x -4,472,815 = 4,472,815
Notice both answers equal 4,472,815
With that explanation out of the way, let's continue. Next, we take the number 4,472,815 and divide it by 2:
4,472,815 ÷ 2 = 2,236,407.5
If the quotient is a whole number, then 2 and 2,236,407.5 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 | 4,472,815 | |
| -1 | -4,472,815 |
Now, we try dividing 4,472,815 by 3:
4,472,815 ÷ 3 = 1,490,938.3333
If the quotient is a whole number, then 3 and 1,490,938.3333 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 | 4,472,815 | |
| -1 | -4,472,815 |
Let's try dividing by 4:
4,472,815 ÷ 4 = 1,118,203.75
If the quotient is a whole number, then 4 and 1,118,203.75 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 | 4,472,815 | |
| -1 | 4,472,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 109 | 145 | 283 | 545 | 1,415 | 3,161 | 8,207 | 15,805 | 30,847 | 41,035 | 154,235 | 894,563 | 4,472,815 |
| -1 | -5 | -29 | -109 | -145 | -283 | -545 | -1,415 | -3,161 | -8,207 | -15,805 | -30,847 | -41,035 | -154,235 | -894,563 | -4,472,815 |
