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 148,792,157, 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 | 148,792,157 | |
| -1 | -148,792,157 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 148,792,157.
Example:
1 x 148,792,157 = 148,792,157
and
-1 x -148,792,157 = 148,792,157
Notice both answers equal 148,792,157
With that explanation out of the way, let's continue. Next, we take the number 148,792,157 and divide it by 2:
148,792,157 ÷ 2 = 74,396,078.5
If the quotient is a whole number, then 2 and 74,396,078.5 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 | 148,792,157 | |
| -1 | -148,792,157 |
Now, we try dividing 148,792,157 by 3:
148,792,157 ÷ 3 = 49,597,385.6667
If the quotient is a whole number, then 3 and 49,597,385.6667 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 | 148,792,157 | |
| -1 | -148,792,157 |
Let's try dividing by 4:
148,792,157 ÷ 4 = 37,198,039.25
If the quotient is a whole number, then 4 and 37,198,039.25 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 | 148,792,157 | |
| -1 | 148,792,157 |
If you did it right, you will end up with this table:
| 1 | 31 | 41 | 167 | 701 | 1,271 | 5,177 | 6,847 | 21,731 | 28,741 | 117,067 | 212,257 | 890,971 | 3,629,077 | 4,799,747 | 148,792,157 |
| -1 | -31 | -41 | -167 | -701 | -1,271 | -5,177 | -6,847 | -21,731 | -28,741 | -117,067 | -212,257 | -890,971 | -3,629,077 | -4,799,747 | -148,792,157 |
