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 146,478,179, 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 | 146,478,179 | |
| -1 | -146,478,179 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 146,478,179.
Example:
1 x 146,478,179 = 146,478,179
and
-1 x -146,478,179 = 146,478,179
Notice both answers equal 146,478,179
With that explanation out of the way, let's continue. Next, we take the number 146,478,179 and divide it by 2:
146,478,179 ÷ 2 = 73,239,089.5
If the quotient is a whole number, then 2 and 73,239,089.5 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 | 146,478,179 | |
| -1 | -146,478,179 |
Now, we try dividing 146,478,179 by 3:
146,478,179 ÷ 3 = 48,826,059.6667
If the quotient is a whole number, then 3 and 48,826,059.6667 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 | 146,478,179 | |
| -1 | -146,478,179 |
Let's try dividing by 4:
146,478,179 ÷ 4 = 36,619,544.75
If the quotient is a whole number, then 4 and 36,619,544.75 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 | 146,478,179 | |
| -1 | 146,478,179 |
If you did it right, you will end up with this table:
| 1 | 47 | 59 | 101 | 523 | 2,773 | 4,747 | 5,959 | 24,581 | 30,857 | 52,823 | 280,073 | 1,450,279 | 2,482,681 | 3,116,557 | 146,478,179 |
| -1 | -47 | -59 | -101 | -523 | -2,773 | -4,747 | -5,959 | -24,581 | -30,857 | -52,823 | -280,073 | -1,450,279 | -2,482,681 | -3,116,557 | -146,478,179 |
