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 68,814,767, 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 | 68,814,767 | |
| -1 | -68,814,767 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,814,767.
Example:
1 x 68,814,767 = 68,814,767
and
-1 x -68,814,767 = 68,814,767
Notice both answers equal 68,814,767
With that explanation out of the way, let's continue. Next, we take the number 68,814,767 and divide it by 2:
68,814,767 ÷ 2 = 34,407,383.5
If the quotient is a whole number, then 2 and 34,407,383.5 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 | 68,814,767 | |
| -1 | -68,814,767 |
Now, we try dividing 68,814,767 by 3:
68,814,767 ÷ 3 = 22,938,255.6667
If the quotient is a whole number, then 3 and 22,938,255.6667 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 | 68,814,767 | |
| -1 | -68,814,767 |
Let's try dividing by 4:
68,814,767 ÷ 4 = 17,203,691.75
If the quotient is a whole number, then 4 and 17,203,691.75 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 | 68,814,767 | |
| -1 | 68,814,767 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 49 | 79 | 203 | 553 | 613 | 1,421 | 2,291 | 3,871 | 4,291 | 16,037 | 17,777 | 30,037 | 48,427 | 112,259 | 124,439 | 338,989 | 871,073 | 1,404,383 | 2,372,923 | 9,830,681 | 68,814,767 |
| -1 | -7 | -29 | -49 | -79 | -203 | -553 | -613 | -1,421 | -2,291 | -3,871 | -4,291 | -16,037 | -17,777 | -30,037 | -48,427 | -112,259 | -124,439 | -338,989 | -871,073 | -1,404,383 | -2,372,923 | -9,830,681 | -68,814,767 |
