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 766,570,417, 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 | 766,570,417 | |
| -1 | -766,570,417 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 766,570,417.
Example:
1 x 766,570,417 = 766,570,417
and
-1 x -766,570,417 = 766,570,417
Notice both answers equal 766,570,417
With that explanation out of the way, let's continue. Next, we take the number 766,570,417 and divide it by 2:
766,570,417 ÷ 2 = 383,285,208.5
If the quotient is a whole number, then 2 and 383,285,208.5 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 | 766,570,417 | |
| -1 | -766,570,417 |
Now, we try dividing 766,570,417 by 3:
766,570,417 ÷ 3 = 255,523,472.3333
If the quotient is a whole number, then 3 and 255,523,472.3333 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 | 766,570,417 | |
| -1 | -766,570,417 |
Let's try dividing by 4:
766,570,417 ÷ 4 = 191,642,604.25
If the quotient is a whole number, then 4 and 191,642,604.25 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 | 766,570,417 | |
| -1 | 766,570,417 |
If you did it right, you will end up with this table:
| 1 | 43 | 79 | 113 | 1,997 | 3,397 | 4,859 | 8,927 | 85,871 | 157,763 | 225,661 | 383,861 | 6,783,809 | 9,703,423 | 17,827,219 | 766,570,417 |
| -1 | -43 | -79 | -113 | -1,997 | -3,397 | -4,859 | -8,927 | -85,871 | -157,763 | -225,661 | -383,861 | -6,783,809 | -9,703,423 | -17,827,219 | -766,570,417 |
