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 245,224,001, 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 | 245,224,001 | |
| -1 | -245,224,001 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 245,224,001.
Example:
1 x 245,224,001 = 245,224,001
and
-1 x -245,224,001 = 245,224,001
Notice both answers equal 245,224,001
With that explanation out of the way, let's continue. Next, we take the number 245,224,001 and divide it by 2:
245,224,001 ÷ 2 = 122,612,000.5
If the quotient is a whole number, then 2 and 122,612,000.5 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 | 245,224,001 | |
| -1 | -245,224,001 |
Now, we try dividing 245,224,001 by 3:
245,224,001 ÷ 3 = 81,741,333.6667
If the quotient is a whole number, then 3 and 81,741,333.6667 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 | 245,224,001 | |
| -1 | -245,224,001 |
Let's try dividing by 4:
245,224,001 ÷ 4 = 61,306,000.25
If the quotient is a whole number, then 4 and 61,306,000.25 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 | 245,224,001 | |
| -1 | 245,224,001 |
If you did it right, you will end up with this table:
| 1 | 11 | 59 | 373 | 649 | 1,013 | 4,103 | 11,143 | 22,007 | 59,767 | 242,077 | 377,849 | 657,437 | 4,156,339 | 22,293,091 | 245,224,001 |
| -1 | -11 | -59 | -373 | -649 | -1,013 | -4,103 | -11,143 | -22,007 | -59,767 | -242,077 | -377,849 | -657,437 | -4,156,339 | -22,293,091 | -245,224,001 |
