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 761,763,035, 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 | 761,763,035 | |
| -1 | -761,763,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 761,763,035.
Example:
1 x 761,763,035 = 761,763,035
and
-1 x -761,763,035 = 761,763,035
Notice both answers equal 761,763,035
With that explanation out of the way, let's continue. Next, we take the number 761,763,035 and divide it by 2:
761,763,035 ÷ 2 = 380,881,517.5
If the quotient is a whole number, then 2 and 380,881,517.5 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 | 761,763,035 | |
| -1 | -761,763,035 |
Now, we try dividing 761,763,035 by 3:
761,763,035 ÷ 3 = 253,921,011.6667
If the quotient is a whole number, then 3 and 253,921,011.6667 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 | 761,763,035 | |
| -1 | -761,763,035 |
Let's try dividing by 4:
761,763,035 ÷ 4 = 190,440,758.75
If the quotient is a whole number, then 4 and 190,440,758.75 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 | 761,763,035 | |
| -1 | 761,763,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 131 | 655 | 1,441 | 7,205 | 105,727 | 528,635 | 1,162,997 | 5,814,985 | 13,850,237 | 69,251,185 | 152,352,607 | 761,763,035 |
| -1 | -5 | -11 | -55 | -131 | -655 | -1,441 | -7,205 | -105,727 | -528,635 | -1,162,997 | -5,814,985 | -13,850,237 | -69,251,185 | -152,352,607 | -761,763,035 |
