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 760,140,305, 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 | 760,140,305 | |
| -1 | -760,140,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 760,140,305.
Example:
1 x 760,140,305 = 760,140,305
and
-1 x -760,140,305 = 760,140,305
Notice both answers equal 760,140,305
With that explanation out of the way, let's continue. Next, we take the number 760,140,305 and divide it by 2:
760,140,305 ÷ 2 = 380,070,152.5
If the quotient is a whole number, then 2 and 380,070,152.5 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 | 760,140,305 | |
| -1 | -760,140,305 |
Now, we try dividing 760,140,305 by 3:
760,140,305 ÷ 3 = 253,380,101.6667
If the quotient is a whole number, then 3 and 253,380,101.6667 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 | 760,140,305 | |
| -1 | -760,140,305 |
Let's try dividing by 4:
760,140,305 ÷ 4 = 190,035,076.25
If the quotient is a whole number, then 4 and 190,035,076.25 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 | 760,140,305 | |
| -1 | 760,140,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 107 | 155 | 535 | 3,317 | 16,585 | 45,833 | 229,165 | 1,420,823 | 4,904,131 | 7,104,115 | 24,520,655 | 152,028,061 | 760,140,305 |
| -1 | -5 | -31 | -107 | -155 | -535 | -3,317 | -16,585 | -45,833 | -229,165 | -1,420,823 | -4,904,131 | -7,104,115 | -24,520,655 | -152,028,061 | -760,140,305 |
