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 761,776,225, 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 | 761,776,225 | |
| -1 | -761,776,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 761,776,225.
Example:
1 x 761,776,225 = 761,776,225
and
-1 x -761,776,225 = 761,776,225
Notice both answers equal 761,776,225
With that explanation out of the way, let's continue. Next, we take the number 761,776,225 and divide it by 2:
761,776,225 ÷ 2 = 380,888,112.5
If the quotient is a whole number, then 2 and 380,888,112.5 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 | 761,776,225 | |
| -1 | -761,776,225 |
Now, we try dividing 761,776,225 by 3:
761,776,225 ÷ 3 = 253,925,408.3333
If the quotient is a whole number, then 3 and 253,925,408.3333 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 | 761,776,225 | |
| -1 | -761,776,225 |
Let's try dividing by 4:
761,776,225 ÷ 4 = 190,444,056.25
If the quotient is a whole number, then 4 and 190,444,056.25 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 | 761,776,225 | |
| -1 | 761,776,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 4,353,007 | 21,765,035 | 30,471,049 | 108,825,175 | 152,355,245 | 761,776,225 |
| -1 | -5 | -7 | -25 | -35 | -175 | -4,353,007 | -21,765,035 | -30,471,049 | -108,825,175 | -152,355,245 | -761,776,225 |
