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 72,767,233, 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 | 72,767,233 | |
| -1 | -72,767,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 72,767,233.
Example:
1 x 72,767,233 = 72,767,233
and
-1 x -72,767,233 = 72,767,233
Notice both answers equal 72,767,233
With that explanation out of the way, let's continue. Next, we take the number 72,767,233 and divide it by 2:
72,767,233 ÷ 2 = 36,383,616.5
If the quotient is a whole number, then 2 and 36,383,616.5 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 | 72,767,233 | |
| -1 | -72,767,233 |
Now, we try dividing 72,767,233 by 3:
72,767,233 ÷ 3 = 24,255,744.3333
If the quotient is a whole number, then 3 and 24,255,744.3333 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 | 72,767,233 | |
| -1 | -72,767,233 |
Let's try dividing by 4:
72,767,233 ÷ 4 = 18,191,808.25
If the quotient is a whole number, then 4 and 18,191,808.25 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 | 72,767,233 | |
| -1 | 72,767,233 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 47 | 77 | 329 | 517 | 3,619 | 20,107 | 140,749 | 221,177 | 945,029 | 1,548,239 | 6,615,203 | 10,395,319 | 72,767,233 |
| -1 | -7 | -11 | -47 | -77 | -329 | -517 | -3,619 | -20,107 | -140,749 | -221,177 | -945,029 | -1,548,239 | -6,615,203 | -10,395,319 | -72,767,233 |
