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 152,040,463, 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 | 152,040,463 | |
| -1 | -152,040,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,040,463.
Example:
1 x 152,040,463 = 152,040,463
and
-1 x -152,040,463 = 152,040,463
Notice both answers equal 152,040,463
With that explanation out of the way, let's continue. Next, we take the number 152,040,463 and divide it by 2:
152,040,463 ÷ 2 = 76,020,231.5
If the quotient is a whole number, then 2 and 76,020,231.5 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 | 152,040,463 | |
| -1 | -152,040,463 |
Now, we try dividing 152,040,463 by 3:
152,040,463 ÷ 3 = 50,680,154.3333
If the quotient is a whole number, then 3 and 50,680,154.3333 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 | 152,040,463 | |
| -1 | -152,040,463 |
Let's try dividing by 4:
152,040,463 ÷ 4 = 38,010,115.75
If the quotient is a whole number, then 4 and 38,010,115.75 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 | 152,040,463 | |
| -1 | 152,040,463 |
If you did it right, you will end up with this table:
| 1 | 59 | 103 | 127 | 197 | 6,077 | 7,493 | 11,623 | 13,081 | 20,291 | 25,019 | 771,779 | 1,197,169 | 1,476,121 | 2,576,957 | 152,040,463 |
| -1 | -59 | -103 | -127 | -197 | -6,077 | -7,493 | -11,623 | -13,081 | -20,291 | -25,019 | -771,779 | -1,197,169 | -1,476,121 | -2,576,957 | -152,040,463 |
