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 145,234,999, 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 | 145,234,999 | |
| -1 | -145,234,999 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,234,999.
Example:
1 x 145,234,999 = 145,234,999
and
-1 x -145,234,999 = 145,234,999
Notice both answers equal 145,234,999
With that explanation out of the way, let's continue. Next, we take the number 145,234,999 and divide it by 2:
145,234,999 ÷ 2 = 72,617,499.5
If the quotient is a whole number, then 2 and 72,617,499.5 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 | 145,234,999 | |
| -1 | -145,234,999 |
Now, we try dividing 145,234,999 by 3:
145,234,999 ÷ 3 = 48,411,666.3333
If the quotient is a whole number, then 3 and 48,411,666.3333 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 | 145,234,999 | |
| -1 | -145,234,999 |
Let's try dividing by 4:
145,234,999 ÷ 4 = 36,308,749.75
If the quotient is a whole number, then 4 and 36,308,749.75 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 | 145,234,999 | |
| -1 | 145,234,999 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 53 | 91 | 371 | 689 | 4,823 | 30,113 | 210,791 | 391,469 | 1,595,989 | 2,740,283 | 11,171,923 | 20,747,857 | 145,234,999 |
| -1 | -7 | -13 | -53 | -91 | -371 | -689 | -4,823 | -30,113 | -210,791 | -391,469 | -1,595,989 | -2,740,283 | -11,171,923 | -20,747,857 | -145,234,999 |
