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 148,494,007, 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 | 148,494,007 | |
| -1 | -148,494,007 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 148,494,007.
Example:
1 x 148,494,007 = 148,494,007
and
-1 x -148,494,007 = 148,494,007
Notice both answers equal 148,494,007
With that explanation out of the way, let's continue. Next, we take the number 148,494,007 and divide it by 2:
148,494,007 ÷ 2 = 74,247,003.5
If the quotient is a whole number, then 2 and 74,247,003.5 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 | 148,494,007 | |
| -1 | -148,494,007 |
Now, we try dividing 148,494,007 by 3:
148,494,007 ÷ 3 = 49,498,002.3333
If the quotient is a whole number, then 3 and 49,498,002.3333 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 | 148,494,007 | |
| -1 | -148,494,007 |
Let's try dividing by 4:
148,494,007 ÷ 4 = 37,123,501.75
If the quotient is a whole number, then 4 and 37,123,501.75 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 | 148,494,007 | |
| -1 | 148,494,007 |
If you did it right, you will end up with this table:
| 1 | 29 | 43 | 193 | 617 | 1,247 | 5,597 | 8,299 | 17,893 | 26,531 | 119,081 | 240,671 | 769,399 | 3,453,349 | 5,120,483 | 148,494,007 |
| -1 | -29 | -43 | -193 | -617 | -1,247 | -5,597 | -8,299 | -17,893 | -26,531 | -119,081 | -240,671 | -769,399 | -3,453,349 | -5,120,483 | -148,494,007 |
