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 762,241,415, 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 | 762,241,415 | |
| -1 | -762,241,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 762,241,415.
Example:
1 x 762,241,415 = 762,241,415
and
-1 x -762,241,415 = 762,241,415
Notice both answers equal 762,241,415
With that explanation out of the way, let's continue. Next, we take the number 762,241,415 and divide it by 2:
762,241,415 ÷ 2 = 381,120,707.5
If the quotient is a whole number, then 2 and 381,120,707.5 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 | 762,241,415 | |
| -1 | -762,241,415 |
Now, we try dividing 762,241,415 by 3:
762,241,415 ÷ 3 = 254,080,471.6667
If the quotient is a whole number, then 3 and 254,080,471.6667 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 | 762,241,415 | |
| -1 | -762,241,415 |
Let's try dividing by 4:
762,241,415 ÷ 4 = 190,560,353.75
If the quotient is a whole number, then 4 and 190,560,353.75 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 | 762,241,415 | |
| -1 | 762,241,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 1,783 | 6,577 | 8,915 | 23,179 | 32,885 | 85,501 | 115,895 | 427,505 | 11,726,791 | 58,633,955 | 152,448,283 | 762,241,415 |
| -1 | -5 | -13 | -65 | -1,783 | -6,577 | -8,915 | -23,179 | -32,885 | -85,501 | -115,895 | -427,505 | -11,726,791 | -58,633,955 | -152,448,283 | -762,241,415 |
