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 763,564,265, 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 | 763,564,265 | |
| -1 | -763,564,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 763,564,265.
Example:
1 x 763,564,265 = 763,564,265
and
-1 x -763,564,265 = 763,564,265
Notice both answers equal 763,564,265
With that explanation out of the way, let's continue. Next, we take the number 763,564,265 and divide it by 2:
763,564,265 ÷ 2 = 381,782,132.5
If the quotient is a whole number, then 2 and 381,782,132.5 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 | 763,564,265 | |
| -1 | -763,564,265 |
Now, we try dividing 763,564,265 by 3:
763,564,265 ÷ 3 = 254,521,421.6667
If the quotient is a whole number, then 3 and 254,521,421.6667 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 | 763,564,265 | |
| -1 | -763,564,265 |
Let's try dividing by 4:
763,564,265 ÷ 4 = 190,891,066.25
If the quotient is a whole number, then 4 and 190,891,066.25 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 | 763,564,265 | |
| -1 | 763,564,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 223 | 1,115 | 3,791 | 18,955 | 40,283 | 201,415 | 684,811 | 3,424,055 | 8,983,109 | 44,915,545 | 152,712,853 | 763,564,265 |
| -1 | -5 | -17 | -85 | -223 | -1,115 | -3,791 | -18,955 | -40,283 | -201,415 | -684,811 | -3,424,055 | -8,983,109 | -44,915,545 | -152,712,853 | -763,564,265 |
