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 22,470,445, 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 | 22,470,445 | |
| -1 | -22,470,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,470,445.
Example:
1 x 22,470,445 = 22,470,445
and
-1 x -22,470,445 = 22,470,445
Notice both answers equal 22,470,445
With that explanation out of the way, let's continue. Next, we take the number 22,470,445 and divide it by 2:
22,470,445 ÷ 2 = 11,235,222.5
If the quotient is a whole number, then 2 and 11,235,222.5 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 | 22,470,445 | |
| -1 | -22,470,445 |
Now, we try dividing 22,470,445 by 3:
22,470,445 ÷ 3 = 7,490,148.3333
If the quotient is a whole number, then 3 and 7,490,148.3333 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 | 22,470,445 | |
| -1 | -22,470,445 |
Let's try dividing by 4:
22,470,445 ÷ 4 = 5,617,611.25
If the quotient is a whole number, then 4 and 5,617,611.25 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 | 22,470,445 | |
| -1 | 22,470,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 59 | 95 | 211 | 295 | 361 | 1,055 | 1,121 | 1,805 | 4,009 | 5,605 | 12,449 | 20,045 | 21,299 | 62,245 | 76,171 | 106,495 | 236,531 | 380,855 | 1,182,655 | 4,494,089 | 22,470,445 |
| -1 | -5 | -19 | -59 | -95 | -211 | -295 | -361 | -1,055 | -1,121 | -1,805 | -4,009 | -5,605 | -12,449 | -20,045 | -21,299 | -62,245 | -76,171 | -106,495 | -236,531 | -380,855 | -1,182,655 | -4,494,089 | -22,470,445 |
