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 244,002,427, 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 | 244,002,427 | |
| -1 | -244,002,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 244,002,427.
Example:
1 x 244,002,427 = 244,002,427
and
-1 x -244,002,427 = 244,002,427
Notice both answers equal 244,002,427
With that explanation out of the way, let's continue. Next, we take the number 244,002,427 and divide it by 2:
244,002,427 ÷ 2 = 122,001,213.5
If the quotient is a whole number, then 2 and 122,001,213.5 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 | 244,002,427 | |
| -1 | -244,002,427 |
Now, we try dividing 244,002,427 by 3:
244,002,427 ÷ 3 = 81,334,142.3333
If the quotient is a whole number, then 3 and 81,334,142.3333 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 | 244,002,427 | |
| -1 | -244,002,427 |
Let's try dividing by 4:
244,002,427 ÷ 4 = 61,000,606.75
If the quotient is a whole number, then 4 and 61,000,606.75 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 | 244,002,427 | |
| -1 | 244,002,427 |
If you did it right, you will end up with this table:
| 1 | 19 | 47 | 73 | 197 | 361 | 893 | 1,387 | 3,431 | 3,743 | 9,259 | 14,381 | 16,967 | 26,353 | 65,189 | 71,117 | 175,921 | 273,239 | 675,907 | 1,238,591 | 3,342,499 | 5,191,541 | 12,842,233 | 244,002,427 |
| -1 | -19 | -47 | -73 | -197 | -361 | -893 | -1,387 | -3,431 | -3,743 | -9,259 | -14,381 | -16,967 | -26,353 | -65,189 | -71,117 | -175,921 | -273,239 | -675,907 | -1,238,591 | -3,342,499 | -5,191,541 | -12,842,233 | -244,002,427 |
