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 245,602,063, 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 | 245,602,063 | |
| -1 | -245,602,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 245,602,063.
Example:
1 x 245,602,063 = 245,602,063
and
-1 x -245,602,063 = 245,602,063
Notice both answers equal 245,602,063
With that explanation out of the way, let's continue. Next, we take the number 245,602,063 and divide it by 2:
245,602,063 ÷ 2 = 122,801,031.5
If the quotient is a whole number, then 2 and 122,801,031.5 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 | 245,602,063 | |
| -1 | -245,602,063 |
Now, we try dividing 245,602,063 by 3:
245,602,063 ÷ 3 = 81,867,354.3333
If the quotient is a whole number, then 3 and 81,867,354.3333 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 | 245,602,063 | |
| -1 | -245,602,063 |
Let's try dividing by 4:
245,602,063 ÷ 4 = 61,400,515.75
If the quotient is a whole number, then 4 and 61,400,515.75 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 | 245,602,063 | |
| -1 | 245,602,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 83 | 343 | 581 | 4,067 | 8,627 | 28,469 | 60,389 | 422,723 | 716,041 | 2,959,061 | 5,012,287 | 35,086,009 | 245,602,063 |
| -1 | -7 | -49 | -83 | -343 | -581 | -4,067 | -8,627 | -28,469 | -60,389 | -422,723 | -716,041 | -2,959,061 | -5,012,287 | -35,086,009 | -245,602,063 |
