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 153,203,453, 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 | 153,203,453 | |
| -1 | -153,203,453 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,203,453.
Example:
1 x 153,203,453 = 153,203,453
and
-1 x -153,203,453 = 153,203,453
Notice both answers equal 153,203,453
With that explanation out of the way, let's continue. Next, we take the number 153,203,453 and divide it by 2:
153,203,453 ÷ 2 = 76,601,726.5
If the quotient is a whole number, then 2 and 76,601,726.5 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 | 153,203,453 | |
| -1 | -153,203,453 |
Now, we try dividing 153,203,453 by 3:
153,203,453 ÷ 3 = 51,067,817.6667
If the quotient is a whole number, then 3 and 51,067,817.6667 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 | 153,203,453 | |
| -1 | -153,203,453 |
Let's try dividing by 4:
153,203,453 ÷ 4 = 38,300,863.25
If the quotient is a whole number, then 4 and 38,300,863.25 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 | 153,203,453 | |
| -1 | 153,203,453 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 223 | 559 | 1,229 | 2,899 | 9,589 | 15,977 | 52,847 | 124,657 | 274,067 | 687,011 | 3,562,871 | 11,784,881 | 153,203,453 |
| -1 | -13 | -43 | -223 | -559 | -1,229 | -2,899 | -9,589 | -15,977 | -52,847 | -124,657 | -274,067 | -687,011 | -3,562,871 | -11,784,881 | -153,203,453 |
