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 245,534,345, 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 | 245,534,345 | |
| -1 | -245,534,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 245,534,345.
Example:
1 x 245,534,345 = 245,534,345
and
-1 x -245,534,345 = 245,534,345
Notice both answers equal 245,534,345
With that explanation out of the way, let's continue. Next, we take the number 245,534,345 and divide it by 2:
245,534,345 ÷ 2 = 122,767,172.5
If the quotient is a whole number, then 2 and 122,767,172.5 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 | 245,534,345 | |
| -1 | -245,534,345 |
Now, we try dividing 245,534,345 by 3:
245,534,345 ÷ 3 = 81,844,781.6667
If the quotient is a whole number, then 3 and 81,844,781.6667 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 | 245,534,345 | |
| -1 | -245,534,345 |
Let's try dividing by 4:
245,534,345 ÷ 4 = 61,383,586.25
If the quotient is a whole number, then 4 and 61,383,586.25 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 | 245,534,345 | |
| -1 | 245,534,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 49 | 235 | 245 | 329 | 1,645 | 2,303 | 11,515 | 21,323 | 106,615 | 149,261 | 746,305 | 1,002,181 | 1,044,827 | 5,010,905 | 5,224,135 | 7,015,267 | 35,076,335 | 49,106,869 | 245,534,345 |
| -1 | -5 | -7 | -35 | -47 | -49 | -235 | -245 | -329 | -1,645 | -2,303 | -11,515 | -21,323 | -106,615 | -149,261 | -746,305 | -1,002,181 | -1,044,827 | -5,010,905 | -5,224,135 | -7,015,267 | -35,076,335 | -49,106,869 | -245,534,345 |
