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 761,816,737, 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 | 761,816,737 | |
| -1 | -761,816,737 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 761,816,737.
Example:
1 x 761,816,737 = 761,816,737
and
-1 x -761,816,737 = 761,816,737
Notice both answers equal 761,816,737
With that explanation out of the way, let's continue. Next, we take the number 761,816,737 and divide it by 2:
761,816,737 ÷ 2 = 380,908,368.5
If the quotient is a whole number, then 2 and 380,908,368.5 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 | 761,816,737 | |
| -1 | -761,816,737 |
Now, we try dividing 761,816,737 by 3:
761,816,737 ÷ 3 = 253,938,912.3333
If the quotient is a whole number, then 3 and 253,938,912.3333 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 | 761,816,737 | |
| -1 | -761,816,737 |
Let's try dividing by 4:
761,816,737 ÷ 4 = 190,454,184.25
If the quotient is a whole number, then 4 and 190,454,184.25 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 | 761,816,737 | |
| -1 | 761,816,737 |
If you did it right, you will end up with this table:
| 1 | 11 | 103 | 509 | 1,133 | 1,321 | 5,599 | 14,531 | 52,427 | 136,063 | 576,697 | 672,389 | 1,496,693 | 7,396,279 | 69,256,067 | 761,816,737 |
| -1 | -11 | -103 | -509 | -1,133 | -1,321 | -5,599 | -14,531 | -52,427 | -136,063 | -576,697 | -672,389 | -1,496,693 | -7,396,279 | -69,256,067 | -761,816,737 |
