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 146,874,079, 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 | 146,874,079 | |
| -1 | -146,874,079 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,874,079.
Example:
1 x 146,874,079 = 146,874,079
and
-1 x -146,874,079 = 146,874,079
Notice both answers equal 146,874,079
With that explanation out of the way, let's continue. Next, we take the number 146,874,079 and divide it by 2:
146,874,079 ÷ 2 = 73,437,039.5
If the quotient is a whole number, then 2 and 73,437,039.5 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 | 146,874,079 | |
| -1 | -146,874,079 |
Now, we try dividing 146,874,079 by 3:
146,874,079 ÷ 3 = 48,958,026.3333
If the quotient is a whole number, then 3 and 48,958,026.3333 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 | 146,874,079 | |
| -1 | -146,874,079 |
Let's try dividing by 4:
146,874,079 ÷ 4 = 36,718,519.75
If the quotient is a whole number, then 4 and 36,718,519.75 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 | 146,874,079 | |
| -1 | 146,874,079 |
If you did it right, you will end up with this table:
| 1 | 11 | 71 | 181 | 781 | 1,039 | 1,991 | 11,429 | 12,851 | 73,769 | 141,361 | 188,059 | 811,459 | 2,068,649 | 13,352,189 | 146,874,079 |
| -1 | -11 | -71 | -181 | -781 | -1,039 | -1,991 | -11,429 | -12,851 | -73,769 | -141,361 | -188,059 | -811,459 | -2,068,649 | -13,352,189 | -146,874,079 |
