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 245,635,495, 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 | 245,635,495 | |
| -1 | -245,635,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 245,635,495.
Example:
1 x 245,635,495 = 245,635,495
and
-1 x -245,635,495 = 245,635,495
Notice both answers equal 245,635,495
With that explanation out of the way, let's continue. Next, we take the number 245,635,495 and divide it by 2:
245,635,495 ÷ 2 = 122,817,747.5
If the quotient is a whole number, then 2 and 122,817,747.5 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 | 245,635,495 | |
| -1 | -245,635,495 |
Now, we try dividing 245,635,495 by 3:
245,635,495 ÷ 3 = 81,878,498.3333
If the quotient is a whole number, then 3 and 81,878,498.3333 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 | 245,635,495 | |
| -1 | -245,635,495 |
Let's try dividing by 4:
245,635,495 ÷ 4 = 61,408,873.75
If the quotient is a whole number, then 4 and 61,408,873.75 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 | 245,635,495 | |
| -1 | 245,635,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 487 | 2,435 | 3,409 | 14,411 | 17,045 | 72,055 | 100,877 | 504,385 | 7,018,157 | 35,090,785 | 49,127,099 | 245,635,495 |
| -1 | -5 | -7 | -35 | -487 | -2,435 | -3,409 | -14,411 | -17,045 | -72,055 | -100,877 | -504,385 | -7,018,157 | -35,090,785 | -49,127,099 | -245,635,495 |
