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 611,304,607, 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 | 611,304,607 | |
| -1 | -611,304,607 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 611,304,607.
Example:
1 x 611,304,607 = 611,304,607
and
-1 x -611,304,607 = 611,304,607
Notice both answers equal 611,304,607
With that explanation out of the way, let's continue. Next, we take the number 611,304,607 and divide it by 2:
611,304,607 ÷ 2 = 305,652,303.5
If the quotient is a whole number, then 2 and 305,652,303.5 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 | 611,304,607 | |
| -1 | -611,304,607 |
Now, we try dividing 611,304,607 by 3:
611,304,607 ÷ 3 = 203,768,202.3333
If the quotient is a whole number, then 3 and 203,768,202.3333 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 | 611,304,607 | |
| -1 | -611,304,607 |
Let's try dividing by 4:
611,304,607 ÷ 4 = 152,826,151.75
If the quotient is a whole number, then 4 and 152,826,151.75 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 | 611,304,607 | |
| -1 | 611,304,607 |
If you did it right, you will end up with this table:
| 1 | 47 | 61 | 79 | 2,699 | 2,867 | 3,713 | 4,819 | 126,853 | 164,639 | 213,221 | 226,493 | 7,738,033 | 10,021,387 | 13,006,481 | 611,304,607 |
| -1 | -47 | -61 | -79 | -2,699 | -2,867 | -3,713 | -4,819 | -126,853 | -164,639 | -213,221 | -226,493 | -7,738,033 | -10,021,387 | -13,006,481 | -611,304,607 |
