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 244,426,405, 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 | 244,426,405 | |
| -1 | -244,426,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,426,405.
Example:
1 x 244,426,405 = 244,426,405
and
-1 x -244,426,405 = 244,426,405
Notice both answers equal 244,426,405
With that explanation out of the way, let's continue. Next, we take the number 244,426,405 and divide it by 2:
244,426,405 ÷ 2 = 122,213,202.5
If the quotient is a whole number, then 2 and 122,213,202.5 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 | 244,426,405 | |
| -1 | -244,426,405 |
Now, we try dividing 244,426,405 by 3:
244,426,405 ÷ 3 = 81,475,468.3333
If the quotient is a whole number, then 3 and 81,475,468.3333 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 | 244,426,405 | |
| -1 | -244,426,405 |
Let's try dividing by 4:
244,426,405 ÷ 4 = 61,106,601.25
If the quotient is a whole number, then 4 and 61,106,601.25 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 | 244,426,405 | |
| -1 | 244,426,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 43 | 115 | 215 | 989 | 4,945 | 49,429 | 247,145 | 1,136,867 | 2,125,447 | 5,684,335 | 10,627,235 | 48,885,281 | 244,426,405 |
| -1 | -5 | -23 | -43 | -115 | -215 | -989 | -4,945 | -49,429 | -247,145 | -1,136,867 | -2,125,447 | -5,684,335 | -10,627,235 | -48,885,281 | -244,426,405 |
