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 611,562,102, 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 | 611,562,102 | |
| -1 | -611,562,102 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 611,562,102.
Example:
1 x 611,562,102 = 611,562,102
and
-1 x -611,562,102 = 611,562,102
Notice both answers equal 611,562,102
With that explanation out of the way, let's continue. Next, we take the number 611,562,102 and divide it by 2:
611,562,102 ÷ 2 = 305,781,051
If the quotient is a whole number, then 2 and 305,781,051 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 305,781,051 | 611,562,102 | |
| -1 | -2 | -305,781,051 | -611,562,102 |
Now, we try dividing 611,562,102 by 3:
611,562,102 ÷ 3 = 203,854,034
If the quotient is a whole number, then 3 and 203,854,034 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 203,854,034 | 305,781,051 | 611,562,102 | |
| -1 | -2 | -3 | -203,854,034 | -305,781,051 | -611,562,102 |
Let's try dividing by 4:
611,562,102 ÷ 4 = 152,890,525.5
If the quotient is a whole number, then 4 and 152,890,525.5 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 | 2 | 3 | 203,854,034 | 305,781,051 | 611,562,102 | |
| -1 | -2 | -3 | -203,854,034 | -305,781,051 | 611,562,102 |
If you did it right, you will end up with this table:
| 1 | 2 | 3 | 6 | 113 | 226 | 339 | 678 | 902,009 | 1,804,018 | 2,706,027 | 5,412,054 | 101,927,017 | 203,854,034 | 305,781,051 | 611,562,102 |
| -1 | -2 | -3 | -6 | -113 | -226 | -339 | -678 | -902,009 | -1,804,018 | -2,706,027 | -5,412,054 | -101,927,017 | -203,854,034 | -305,781,051 | -611,562,102 |
