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 68,772,535, 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 | 68,772,535 | |
| -1 | -68,772,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 68,772,535.
Example:
1 x 68,772,535 = 68,772,535
and
-1 x -68,772,535 = 68,772,535
Notice both answers equal 68,772,535
With that explanation out of the way, let's continue. Next, we take the number 68,772,535 and divide it by 2:
68,772,535 ÷ 2 = 34,386,267.5
If the quotient is a whole number, then 2 and 34,386,267.5 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 | 68,772,535 | |
| -1 | -68,772,535 |
Now, we try dividing 68,772,535 by 3:
68,772,535 ÷ 3 = 22,924,178.3333
If the quotient is a whole number, then 3 and 22,924,178.3333 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 | 68,772,535 | |
| -1 | -68,772,535 |
Let's try dividing by 4:
68,772,535 ÷ 4 = 17,193,133.75
If the quotient is a whole number, then 4 and 17,193,133.75 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 | 68,772,535 | |
| -1 | 68,772,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 53 | 65 | 265 | 689 | 3,445 | 19,963 | 99,815 | 259,519 | 1,058,039 | 1,297,595 | 5,290,195 | 13,754,507 | 68,772,535 |
| -1 | -5 | -13 | -53 | -65 | -265 | -689 | -3,445 | -19,963 | -99,815 | -259,519 | -1,058,039 | -1,297,595 | -5,290,195 | -13,754,507 | -68,772,535 |
