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 4,420,445, 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 | 4,420,445 | |
| -1 | -4,420,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,420,445.
Example:
1 x 4,420,445 = 4,420,445
and
-1 x -4,420,445 = 4,420,445
Notice both answers equal 4,420,445
With that explanation out of the way, let's continue. Next, we take the number 4,420,445 and divide it by 2:
4,420,445 ÷ 2 = 2,210,222.5
If the quotient is a whole number, then 2 and 2,210,222.5 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 | 4,420,445 | |
| -1 | -4,420,445 |
Now, we try dividing 4,420,445 by 3:
4,420,445 ÷ 3 = 1,473,481.6667
If the quotient is a whole number, then 3 and 1,473,481.6667 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 | 4,420,445 | |
| -1 | -4,420,445 |
Let's try dividing by 4:
4,420,445 ÷ 4 = 1,105,111.25
If the quotient is a whole number, then 4 and 1,105,111.25 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 | 4,420,445 | |
| -1 | 4,420,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 31 | 79 | 95 | 155 | 361 | 395 | 589 | 1,501 | 1,805 | 2,449 | 2,945 | 7,505 | 11,191 | 12,245 | 28,519 | 46,531 | 55,955 | 142,595 | 232,655 | 884,089 | 4,420,445 |
| -1 | -5 | -19 | -31 | -79 | -95 | -155 | -361 | -395 | -589 | -1,501 | -1,805 | -2,449 | -2,945 | -7,505 | -11,191 | -12,245 | -28,519 | -46,531 | -55,955 | -142,595 | -232,655 | -884,089 | -4,420,445 |
