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 614,065,705, 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 | 614,065,705 | |
| -1 | -614,065,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 614,065,705.
Example:
1 x 614,065,705 = 614,065,705
and
-1 x -614,065,705 = 614,065,705
Notice both answers equal 614,065,705
With that explanation out of the way, let's continue. Next, we take the number 614,065,705 and divide it by 2:
614,065,705 ÷ 2 = 307,032,852.5
If the quotient is a whole number, then 2 and 307,032,852.5 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 | 614,065,705 | |
| -1 | -614,065,705 |
Now, we try dividing 614,065,705 by 3:
614,065,705 ÷ 3 = 204,688,568.3333
If the quotient is a whole number, then 3 and 204,688,568.3333 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 | 614,065,705 | |
| -1 | -614,065,705 |
Let's try dividing by 4:
614,065,705 ÷ 4 = 153,516,426.25
If the quotient is a whole number, then 4 and 153,516,426.25 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 | 614,065,705 | |
| -1 | 614,065,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 397 | 1,985 | 4,367 | 21,835 | 28,123 | 140,615 | 309,353 | 1,546,765 | 11,164,831 | 55,824,155 | 122,813,141 | 614,065,705 |
| -1 | -5 | -11 | -55 | -397 | -1,985 | -4,367 | -21,835 | -28,123 | -140,615 | -309,353 | -1,546,765 | -11,164,831 | -55,824,155 | -122,813,141 | -614,065,705 |
