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 145,302,443, 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 | 145,302,443 | |
| -1 | -145,302,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,302,443.
Example:
1 x 145,302,443 = 145,302,443
and
-1 x -145,302,443 = 145,302,443
Notice both answers equal 145,302,443
With that explanation out of the way, let's continue. Next, we take the number 145,302,443 and divide it by 2:
145,302,443 ÷ 2 = 72,651,221.5
If the quotient is a whole number, then 2 and 72,651,221.5 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 | 145,302,443 | |
| -1 | -145,302,443 |
Now, we try dividing 145,302,443 by 3:
145,302,443 ÷ 3 = 48,434,147.6667
If the quotient is a whole number, then 3 and 48,434,147.6667 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 | 145,302,443 | |
| -1 | -145,302,443 |
Let's try dividing by 4:
145,302,443 ÷ 4 = 36,325,610.75
If the quotient is a whole number, then 4 and 36,325,610.75 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 | 145,302,443 | |
| -1 | 145,302,443 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 19 | 143 | 209 | 247 | 2,717 | 53,479 | 588,269 | 695,227 | 1,016,101 | 7,647,497 | 11,177,111 | 13,209,313 | 145,302,443 |
| -1 | -11 | -13 | -19 | -143 | -209 | -247 | -2,717 | -53,479 | -588,269 | -695,227 | -1,016,101 | -7,647,497 | -11,177,111 | -13,209,313 | -145,302,443 |
