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 145,520,357, 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 | 145,520,357 | |
| -1 | -145,520,357 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,520,357.
Example:
1 x 145,520,357 = 145,520,357
and
-1 x -145,520,357 = 145,520,357
Notice both answers equal 145,520,357
With that explanation out of the way, let's continue. Next, we take the number 145,520,357 and divide it by 2:
145,520,357 ÷ 2 = 72,760,178.5
If the quotient is a whole number, then 2 and 72,760,178.5 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 | 145,520,357 | |
| -1 | -145,520,357 |
Now, we try dividing 145,520,357 by 3:
145,520,357 ÷ 3 = 48,506,785.6667
If the quotient is a whole number, then 3 and 48,506,785.6667 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 | 145,520,357 | |
| -1 | -145,520,357 |
Let's try dividing by 4:
145,520,357 ÷ 4 = 36,380,089.25
If the quotient is a whole number, then 4 and 36,380,089.25 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 | 145,520,357 | |
| -1 | 145,520,357 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 103 | 697 | 1,751 | 2,027 | 4,223 | 34,459 | 71,791 | 83,107 | 208,781 | 1,412,819 | 3,549,277 | 8,560,021 | 145,520,357 |
| -1 | -17 | -41 | -103 | -697 | -1,751 | -2,027 | -4,223 | -34,459 | -71,791 | -83,107 | -208,781 | -1,412,819 | -3,549,277 | -8,560,021 | -145,520,357 |
