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 148,273,027, 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 | 148,273,027 | |
| -1 | -148,273,027 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 148,273,027.
Example:
1 x 148,273,027 = 148,273,027
and
-1 x -148,273,027 = 148,273,027
Notice both answers equal 148,273,027
With that explanation out of the way, let's continue. Next, we take the number 148,273,027 and divide it by 2:
148,273,027 ÷ 2 = 74,136,513.5
If the quotient is a whole number, then 2 and 74,136,513.5 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 | 148,273,027 | |
| -1 | -148,273,027 |
Now, we try dividing 148,273,027 by 3:
148,273,027 ÷ 3 = 49,424,342.3333
If the quotient is a whole number, then 3 and 49,424,342.3333 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 | 148,273,027 | |
| -1 | -148,273,027 |
Let's try dividing by 4:
148,273,027 ÷ 4 = 37,068,256.75
If the quotient is a whole number, then 4 and 37,068,256.75 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 | 148,273,027 | |
| -1 | 148,273,027 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 109 | 203 | 763 | 3,161 | 6,701 | 22,127 | 46,907 | 194,329 | 730,409 | 1,360,303 | 5,112,863 | 21,181,861 | 148,273,027 |
| -1 | -7 | -29 | -109 | -203 | -763 | -3,161 | -6,701 | -22,127 | -46,907 | -194,329 | -730,409 | -1,360,303 | -5,112,863 | -21,181,861 | -148,273,027 |
