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 245,031,061, 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 | 245,031,061 | |
| -1 | -245,031,061 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 245,031,061.
Example:
1 x 245,031,061 = 245,031,061
and
-1 x -245,031,061 = 245,031,061
Notice both answers equal 245,031,061
With that explanation out of the way, let's continue. Next, we take the number 245,031,061 and divide it by 2:
245,031,061 ÷ 2 = 122,515,530.5
If the quotient is a whole number, then 2 and 122,515,530.5 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 | 245,031,061 | |
| -1 | -245,031,061 |
Now, we try dividing 245,031,061 by 3:
245,031,061 ÷ 3 = 81,677,020.3333
If the quotient is a whole number, then 3 and 81,677,020.3333 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 | 245,031,061 | |
| -1 | -245,031,061 |
Let's try dividing by 4:
245,031,061 ÷ 4 = 61,257,765.25
If the quotient is a whole number, then 4 and 61,257,765.25 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 | 245,031,061 | |
| -1 | 245,031,061 |
If you did it right, you will end up with this table:
| 1 | 11 | 79 | 457 | 617 | 869 | 5,027 | 6,787 | 36,103 | 48,743 | 281,969 | 397,133 | 536,173 | 3,101,659 | 22,275,551 | 245,031,061 |
| -1 | -11 | -79 | -457 | -617 | -869 | -5,027 | -6,787 | -36,103 | -48,743 | -281,969 | -397,133 | -536,173 | -3,101,659 | -22,275,551 | -245,031,061 |
