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 761,774,713, 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 | 761,774,713 | |
| -1 | -761,774,713 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 761,774,713.
Example:
1 x 761,774,713 = 761,774,713
and
-1 x -761,774,713 = 761,774,713
Notice both answers equal 761,774,713
With that explanation out of the way, let's continue. Next, we take the number 761,774,713 and divide it by 2:
761,774,713 ÷ 2 = 380,887,356.5
If the quotient is a whole number, then 2 and 380,887,356.5 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 | 761,774,713 | |
| -1 | -761,774,713 |
Now, we try dividing 761,774,713 by 3:
761,774,713 ÷ 3 = 253,924,904.3333
If the quotient is a whole number, then 3 and 253,924,904.3333 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 | 761,774,713 | |
| -1 | -761,774,713 |
Let's try dividing by 4:
761,774,713 ÷ 4 = 190,443,678.25
If the quotient is a whole number, then 4 and 190,443,678.25 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 | 761,774,713 | |
| -1 | 761,774,713 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 103 | 301 | 721 | 4,429 | 24,571 | 31,003 | 171,997 | 1,056,553 | 2,530,813 | 7,395,871 | 17,715,691 | 108,824,959 | 761,774,713 |
| -1 | -7 | -43 | -103 | -301 | -721 | -4,429 | -24,571 | -31,003 | -171,997 | -1,056,553 | -2,530,813 | -7,395,871 | -17,715,691 | -108,824,959 | -761,774,713 |
