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 148,659,775, 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 | 148,659,775 | |
| -1 | -148,659,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 148,659,775.
Example:
1 x 148,659,775 = 148,659,775
and
-1 x -148,659,775 = 148,659,775
Notice both answers equal 148,659,775
With that explanation out of the way, let's continue. Next, we take the number 148,659,775 and divide it by 2:
148,659,775 ÷ 2 = 74,329,887.5
If the quotient is a whole number, then 2 and 74,329,887.5 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 | 148,659,775 | |
| -1 | -148,659,775 |
Now, we try dividing 148,659,775 by 3:
148,659,775 ÷ 3 = 49,553,258.3333
If the quotient is a whole number, then 3 and 49,553,258.3333 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 | 148,659,775 | |
| -1 | -148,659,775 |
Let's try dividing by 4:
148,659,775 ÷ 4 = 37,164,943.75
If the quotient is a whole number, then 4 and 37,164,943.75 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 | 148,659,775 | |
| -1 | 148,659,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 97 | 275 | 485 | 1,067 | 2,425 | 5,335 | 5,573 | 26,675 | 27,865 | 61,303 | 139,325 | 306,515 | 540,581 | 1,532,575 | 2,702,905 | 5,946,391 | 13,514,525 | 29,731,955 | 148,659,775 |
| -1 | -5 | -11 | -25 | -55 | -97 | -275 | -485 | -1,067 | -2,425 | -5,335 | -5,573 | -26,675 | -27,865 | -61,303 | -139,325 | -306,515 | -540,581 | -1,532,575 | -2,702,905 | -5,946,391 | -13,514,525 | -29,731,955 | -148,659,775 |
