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 67,237,027, 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 | 67,237,027 | |
| -1 | -67,237,027 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,237,027.
Example:
1 x 67,237,027 = 67,237,027
and
-1 x -67,237,027 = 67,237,027
Notice both answers equal 67,237,027
With that explanation out of the way, let's continue. Next, we take the number 67,237,027 and divide it by 2:
67,237,027 ÷ 2 = 33,618,513.5
If the quotient is a whole number, then 2 and 33,618,513.5 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 | 67,237,027 | |
| -1 | -67,237,027 |
Now, we try dividing 67,237,027 by 3:
67,237,027 ÷ 3 = 22,412,342.3333
If the quotient is a whole number, then 3 and 22,412,342.3333 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 | 67,237,027 | |
| -1 | -67,237,027 |
Let's try dividing by 4:
67,237,027 ÷ 4 = 16,809,256.75
If the quotient is a whole number, then 4 and 16,809,256.75 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 | 67,237,027 | |
| -1 | 67,237,027 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 23 | 143 | 253 | 299 | 3,289 | 20,443 | 224,873 | 265,759 | 470,189 | 2,923,349 | 5,172,079 | 6,112,457 | 67,237,027 |
| -1 | -11 | -13 | -23 | -143 | -253 | -299 | -3,289 | -20,443 | -224,873 | -265,759 | -470,189 | -2,923,349 | -5,172,079 | -6,112,457 | -67,237,027 |
