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 761,232,055, 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 | 761,232,055 | |
| -1 | -761,232,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 761,232,055.
Example:
1 x 761,232,055 = 761,232,055
and
-1 x -761,232,055 = 761,232,055
Notice both answers equal 761,232,055
With that explanation out of the way, let's continue. Next, we take the number 761,232,055 and divide it by 2:
761,232,055 ÷ 2 = 380,616,027.5
If the quotient is a whole number, then 2 and 380,616,027.5 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 | 761,232,055 | |
| -1 | -761,232,055 |
Now, we try dividing 761,232,055 by 3:
761,232,055 ÷ 3 = 253,744,018.3333
If the quotient is a whole number, then 3 and 253,744,018.3333 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 | 761,232,055 | |
| -1 | -761,232,055 |
Let's try dividing by 4:
761,232,055 ÷ 4 = 190,308,013.75
If the quotient is a whole number, then 4 and 190,308,013.75 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 | 761,232,055 | |
| -1 | 761,232,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 1,693 | 4,733 | 8,465 | 23,665 | 32,167 | 89,927 | 160,835 | 449,635 | 8,012,969 | 40,064,845 | 152,246,411 | 761,232,055 |
| -1 | -5 | -19 | -95 | -1,693 | -4,733 | -8,465 | -23,665 | -32,167 | -89,927 | -160,835 | -449,635 | -8,012,969 | -40,064,845 | -152,246,411 | -761,232,055 |
