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 145,350,737, 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 | 145,350,737 | |
| -1 | -145,350,737 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,350,737.
Example:
1 x 145,350,737 = 145,350,737
and
-1 x -145,350,737 = 145,350,737
Notice both answers equal 145,350,737
With that explanation out of the way, let's continue. Next, we take the number 145,350,737 and divide it by 2:
145,350,737 ÷ 2 = 72,675,368.5
If the quotient is a whole number, then 2 and 72,675,368.5 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 | 145,350,737 | |
| -1 | -145,350,737 |
Now, we try dividing 145,350,737 by 3:
145,350,737 ÷ 3 = 48,450,245.6667
If the quotient is a whole number, then 3 and 48,450,245.6667 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 | 145,350,737 | |
| -1 | -145,350,737 |
Let's try dividing by 4:
145,350,737 ÷ 4 = 36,337,684.25
If the quotient is a whole number, then 4 and 36,337,684.25 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 | 145,350,737 | |
| -1 | 145,350,737 |
If you did it right, you will end up with this table:
| 1 | 7 | 109 | 197 | 763 | 967 | 1,379 | 6,769 | 21,473 | 105,403 | 150,311 | 190,499 | 737,821 | 1,333,493 | 20,764,391 | 145,350,737 |
| -1 | -7 | -109 | -197 | -763 | -967 | -1,379 | -6,769 | -21,473 | -105,403 | -150,311 | -190,499 | -737,821 | -1,333,493 | -20,764,391 | -145,350,737 |
