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 145,404,545, 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 | 145,404,545 | |
| -1 | -145,404,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,404,545.
Example:
1 x 145,404,545 = 145,404,545
and
-1 x -145,404,545 = 145,404,545
Notice both answers equal 145,404,545
With that explanation out of the way, let's continue. Next, we take the number 145,404,545 and divide it by 2:
145,404,545 ÷ 2 = 72,702,272.5
If the quotient is a whole number, then 2 and 72,702,272.5 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 | 145,404,545 | |
| -1 | -145,404,545 |
Now, we try dividing 145,404,545 by 3:
145,404,545 ÷ 3 = 48,468,181.6667
If the quotient is a whole number, then 3 and 48,468,181.6667 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 | 145,404,545 | |
| -1 | -145,404,545 |
Let's try dividing by 4:
145,404,545 ÷ 4 = 36,351,136.25
If the quotient is a whole number, then 4 and 36,351,136.25 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 | 145,404,545 | |
| -1 | 145,404,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 203,363 | 1,016,815 | 2,236,993 | 2,643,719 | 11,184,965 | 13,218,595 | 29,080,909 | 145,404,545 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -203,363 | -1,016,815 | -2,236,993 | -2,643,719 | -11,184,965 | -13,218,595 | -29,080,909 | -145,404,545 |
