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 4,224,451, 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 | 4,224,451 | |
| -1 | -4,224,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,224,451.
Example:
1 x 4,224,451 = 4,224,451
and
-1 x -4,224,451 = 4,224,451
Notice both answers equal 4,224,451
With that explanation out of the way, let's continue. Next, we take the number 4,224,451 and divide it by 2:
4,224,451 ÷ 2 = 2,112,225.5
If the quotient is a whole number, then 2 and 2,112,225.5 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 | 4,224,451 | |
| -1 | -4,224,451 |
Now, we try dividing 4,224,451 by 3:
4,224,451 ÷ 3 = 1,408,150.3333
If the quotient is a whole number, then 3 and 1,408,150.3333 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 | 4,224,451 | |
| -1 | -4,224,451 |
Let's try dividing by 4:
4,224,451 ÷ 4 = 1,056,112.75
If the quotient is a whole number, then 4 and 1,056,112.75 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 | 4,224,451 | |
| -1 | 4,224,451 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 83 | 581 | 661 | 913 | 4,627 | 6,391 | 7,271 | 50,897 | 54,863 | 384,041 | 603,493 | 4,224,451 |
| -1 | -7 | -11 | -77 | -83 | -581 | -661 | -913 | -4,627 | -6,391 | -7,271 | -50,897 | -54,863 | -384,041 | -603,493 | -4,224,451 |
