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 4,772,477, 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 | 4,772,477 | |
| -1 | -4,772,477 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,772,477.
Example:
1 x 4,772,477 = 4,772,477
and
-1 x -4,772,477 = 4,772,477
Notice both answers equal 4,772,477
With that explanation out of the way, let's continue. Next, we take the number 4,772,477 and divide it by 2:
4,772,477 ÷ 2 = 2,386,238.5
If the quotient is a whole number, then 2 and 2,386,238.5 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 | 4,772,477 | |
| -1 | -4,772,477 |
Now, we try dividing 4,772,477 by 3:
4,772,477 ÷ 3 = 1,590,825.6667
If the quotient is a whole number, then 3 and 1,590,825.6667 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 | 4,772,477 | |
| -1 | -4,772,477 |
Let's try dividing by 4:
4,772,477 ÷ 4 = 1,193,119.25
If the quotient is a whole number, then 4 and 1,193,119.25 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 | 4,772,477 | |
| -1 | 4,772,477 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 67 | 163 | 437 | 1,273 | 1,541 | 3,097 | 3,749 | 10,921 | 29,279 | 71,231 | 207,499 | 251,183 | 4,772,477 |
| -1 | -19 | -23 | -67 | -163 | -437 | -1,273 | -1,541 | -3,097 | -3,749 | -10,921 | -29,279 | -71,231 | -207,499 | -251,183 | -4,772,477 |
