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 145,530,049, 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 | 145,530,049 | |
| -1 | -145,530,049 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,530,049.
Example:
1 x 145,530,049 = 145,530,049
and
-1 x -145,530,049 = 145,530,049
Notice both answers equal 145,530,049
With that explanation out of the way, let's continue. Next, we take the number 145,530,049 and divide it by 2:
145,530,049 ÷ 2 = 72,765,024.5
If the quotient is a whole number, then 2 and 72,765,024.5 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 | 145,530,049 | |
| -1 | -145,530,049 |
Now, we try dividing 145,530,049 by 3:
145,530,049 ÷ 3 = 48,510,016.3333
If the quotient is a whole number, then 3 and 48,510,016.3333 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 | 145,530,049 | |
| -1 | -145,530,049 |
Let's try dividing by 4:
145,530,049 ÷ 4 = 36,382,512.25
If the quotient is a whole number, then 4 and 36,382,512.25 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 | 145,530,049 | |
| -1 | 145,530,049 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 59 | 71 | 413 | 497 | 709 | 2,891 | 3,479 | 4,189 | 4,963 | 29,323 | 34,741 | 41,831 | 50,339 | 205,261 | 292,817 | 352,373 | 2,049,719 | 2,466,611 | 2,970,001 | 20,790,007 | 145,530,049 |
| -1 | -7 | -49 | -59 | -71 | -413 | -497 | -709 | -2,891 | -3,479 | -4,189 | -4,963 | -29,323 | -34,741 | -41,831 | -50,339 | -205,261 | -292,817 | -352,373 | -2,049,719 | -2,466,611 | -2,970,001 | -20,790,007 | -145,530,049 |
