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 764,074,577, 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 | 764,074,577 | |
| -1 | -764,074,577 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 764,074,577.
Example:
1 x 764,074,577 = 764,074,577
and
-1 x -764,074,577 = 764,074,577
Notice both answers equal 764,074,577
With that explanation out of the way, let's continue. Next, we take the number 764,074,577 and divide it by 2:
764,074,577 ÷ 2 = 382,037,288.5
If the quotient is a whole number, then 2 and 382,037,288.5 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 | 764,074,577 | |
| -1 | -764,074,577 |
Now, we try dividing 764,074,577 by 3:
764,074,577 ÷ 3 = 254,691,525.6667
If the quotient is a whole number, then 3 and 254,691,525.6667 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 | 764,074,577 | |
| -1 | -764,074,577 |
Let's try dividing by 4:
764,074,577 ÷ 4 = 191,018,644.25
If the quotient is a whole number, then 4 and 191,018,644.25 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 | 764,074,577 | |
| -1 | 764,074,577 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 217 | 409 | 2,863 | 8,609 | 12,679 | 60,263 | 88,753 | 266,879 | 1,868,153 | 3,521,081 | 24,647,567 | 109,153,511 | 764,074,577 |
| -1 | -7 | -31 | -217 | -409 | -2,863 | -8,609 | -12,679 | -60,263 | -88,753 | -266,879 | -1,868,153 | -3,521,081 | -24,647,567 | -109,153,511 | -764,074,577 |
