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 767,477,375, 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 | 767,477,375 | |
| -1 | -767,477,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 767,477,375.
Example:
1 x 767,477,375 = 767,477,375
and
-1 x -767,477,375 = 767,477,375
Notice both answers equal 767,477,375
With that explanation out of the way, let's continue. Next, we take the number 767,477,375 and divide it by 2:
767,477,375 ÷ 2 = 383,738,687.5
If the quotient is a whole number, then 2 and 383,738,687.5 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 | 767,477,375 | |
| -1 | -767,477,375 |
Now, we try dividing 767,477,375 by 3:
767,477,375 ÷ 3 = 255,825,791.6667
If the quotient is a whole number, then 3 and 255,825,791.6667 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 | 767,477,375 | |
| -1 | -767,477,375 |
Let's try dividing by 4:
767,477,375 ÷ 4 = 191,869,343.75
If the quotient is a whole number, then 4 and 191,869,343.75 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 | 767,477,375 | |
| -1 | 767,477,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 877,117 | 4,385,585 | 6,139,819 | 21,927,925 | 30,699,095 | 109,639,625 | 153,495,475 | 767,477,375 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -877,117 | -4,385,585 | -6,139,819 | -21,927,925 | -30,699,095 | -109,639,625 | -153,495,475 | -767,477,375 |
