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 145,433,045, 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 | 145,433,045 | |
| -1 | -145,433,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,433,045.
Example:
1 x 145,433,045 = 145,433,045
and
-1 x -145,433,045 = 145,433,045
Notice both answers equal 145,433,045
With that explanation out of the way, let's continue. Next, we take the number 145,433,045 and divide it by 2:
145,433,045 ÷ 2 = 72,716,522.5
If the quotient is a whole number, then 2 and 72,716,522.5 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 | 145,433,045 | |
| -1 | -145,433,045 |
Now, we try dividing 145,433,045 by 3:
145,433,045 ÷ 3 = 48,477,681.6667
If the quotient is a whole number, then 3 and 48,477,681.6667 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 | 145,433,045 | |
| -1 | -145,433,045 |
Let's try dividing by 4:
145,433,045 ÷ 4 = 36,358,261.25
If the quotient is a whole number, then 4 and 36,358,261.25 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 | 145,433,045 | |
| -1 | 145,433,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 1,223 | 1,399 | 6,115 | 6,995 | 20,791 | 23,783 | 103,955 | 118,915 | 1,710,977 | 8,554,885 | 29,086,609 | 145,433,045 |
| -1 | -5 | -17 | -85 | -1,223 | -1,399 | -6,115 | -6,995 | -20,791 | -23,783 | -103,955 | -118,915 | -1,710,977 | -8,554,885 | -29,086,609 | -145,433,045 |
