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 611,570,305, 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 | 611,570,305 | |
| -1 | -611,570,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 611,570,305.
Example:
1 x 611,570,305 = 611,570,305
and
-1 x -611,570,305 = 611,570,305
Notice both answers equal 611,570,305
With that explanation out of the way, let's continue. Next, we take the number 611,570,305 and divide it by 2:
611,570,305 ÷ 2 = 305,785,152.5
If the quotient is a whole number, then 2 and 305,785,152.5 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 | 611,570,305 | |
| -1 | -611,570,305 |
Now, we try dividing 611,570,305 by 3:
611,570,305 ÷ 3 = 203,856,768.3333
If the quotient is a whole number, then 3 and 203,856,768.3333 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 | 611,570,305 | |
| -1 | -611,570,305 |
Let's try dividing by 4:
611,570,305 ÷ 4 = 152,892,576.25
If the quotient is a whole number, then 4 and 152,892,576.25 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 | 611,570,305 | |
| -1 | 611,570,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 335 | 419 | 2,095 | 4,357 | 21,785 | 28,073 | 140,365 | 291,919 | 1,459,595 | 1,825,583 | 9,127,915 | 122,314,061 | 611,570,305 |
| -1 | -5 | -67 | -335 | -419 | -2,095 | -4,357 | -21,785 | -28,073 | -140,365 | -291,919 | -1,459,595 | -1,825,583 | -9,127,915 | -122,314,061 | -611,570,305 |
