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 153,436,535, 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 | 153,436,535 | |
| -1 | -153,436,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,436,535.
Example:
1 x 153,436,535 = 153,436,535
and
-1 x -153,436,535 = 153,436,535
Notice both answers equal 153,436,535
With that explanation out of the way, let's continue. Next, we take the number 153,436,535 and divide it by 2:
153,436,535 ÷ 2 = 76,718,267.5
If the quotient is a whole number, then 2 and 76,718,267.5 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 | 153,436,535 | |
| -1 | -153,436,535 |
Now, we try dividing 153,436,535 by 3:
153,436,535 ÷ 3 = 51,145,511.6667
If the quotient is a whole number, then 3 and 51,145,511.6667 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 | 153,436,535 | |
| -1 | -153,436,535 |
Let's try dividing by 4:
153,436,535 ÷ 4 = 38,359,133.75
If the quotient is a whole number, then 4 and 38,359,133.75 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 | 153,436,535 | |
| -1 | 153,436,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 151,169 | 755,845 | 1,058,183 | 4,383,901 | 5,290,915 | 21,919,505 | 30,687,307 | 153,436,535 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -151,169 | -755,845 | -1,058,183 | -4,383,901 | -5,290,915 | -21,919,505 | -30,687,307 | -153,436,535 |
