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 761,433,055, 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 | 761,433,055 | |
| -1 | -761,433,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 761,433,055.
Example:
1 x 761,433,055 = 761,433,055
and
-1 x -761,433,055 = 761,433,055
Notice both answers equal 761,433,055
With that explanation out of the way, let's continue. Next, we take the number 761,433,055 and divide it by 2:
761,433,055 ÷ 2 = 380,716,527.5
If the quotient is a whole number, then 2 and 380,716,527.5 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 | 761,433,055 | |
| -1 | -761,433,055 |
Now, we try dividing 761,433,055 by 3:
761,433,055 ÷ 3 = 253,811,018.3333
If the quotient is a whole number, then 3 and 253,811,018.3333 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 | 761,433,055 | |
| -1 | -761,433,055 |
Let's try dividing by 4:
761,433,055 ÷ 4 = 190,358,263.75
If the quotient is a whole number, then 4 and 190,358,263.75 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 | 761,433,055 | |
| -1 | 761,433,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 59 | 115 | 295 | 1,357 | 6,785 | 112,223 | 561,115 | 2,581,129 | 6,621,157 | 12,905,645 | 33,105,785 | 152,286,611 | 761,433,055 |
| -1 | -5 | -23 | -59 | -115 | -295 | -1,357 | -6,785 | -112,223 | -561,115 | -2,581,129 | -6,621,157 | -12,905,645 | -33,105,785 | -152,286,611 | -761,433,055 |
