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 145,462,133, 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 | 145,462,133 | |
| -1 | -145,462,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,462,133.
Example:
1 x 145,462,133 = 145,462,133
and
-1 x -145,462,133 = 145,462,133
Notice both answers equal 145,462,133
With that explanation out of the way, let's continue. Next, we take the number 145,462,133 and divide it by 2:
145,462,133 ÷ 2 = 72,731,066.5
If the quotient is a whole number, then 2 and 72,731,066.5 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 | 145,462,133 | |
| -1 | -145,462,133 |
Now, we try dividing 145,462,133 by 3:
145,462,133 ÷ 3 = 48,487,377.6667
If the quotient is a whole number, then 3 and 48,487,377.6667 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 | 145,462,133 | |
| -1 | -145,462,133 |
Let's try dividing by 4:
145,462,133 ÷ 4 = 36,365,533.25
If the quotient is a whole number, then 4 and 36,365,533.25 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 | 145,462,133 | |
| -1 | 145,462,133 |
If you did it right, you will end up with this table:
| 1 | 37 | 47 | 233 | 359 | 1,739 | 8,621 | 10,951 | 13,283 | 16,873 | 83,647 | 405,187 | 624,301 | 3,094,939 | 3,931,409 | 145,462,133 |
| -1 | -37 | -47 | -233 | -359 | -1,739 | -8,621 | -10,951 | -13,283 | -16,873 | -83,647 | -405,187 | -624,301 | -3,094,939 | -3,931,409 | -145,462,133 |
