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 154,302,035, 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 | 154,302,035 | |
| -1 | -154,302,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,302,035.
Example:
1 x 154,302,035 = 154,302,035
and
-1 x -154,302,035 = 154,302,035
Notice both answers equal 154,302,035
With that explanation out of the way, let's continue. Next, we take the number 154,302,035 and divide it by 2:
154,302,035 ÷ 2 = 77,151,017.5
If the quotient is a whole number, then 2 and 77,151,017.5 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 | 154,302,035 | |
| -1 | -154,302,035 |
Now, we try dividing 154,302,035 by 3:
154,302,035 ÷ 3 = 51,434,011.6667
If the quotient is a whole number, then 3 and 51,434,011.6667 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 | 154,302,035 | |
| -1 | -154,302,035 |
Let's try dividing by 4:
154,302,035 ÷ 4 = 38,575,508.75
If the quotient is a whole number, then 4 and 38,575,508.75 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 | 154,302,035 | |
| -1 | 154,302,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 109 | 155 | 545 | 3,379 | 9,133 | 16,895 | 45,665 | 283,123 | 995,497 | 1,415,615 | 4,977,485 | 30,860,407 | 154,302,035 |
| -1 | -5 | -31 | -109 | -155 | -545 | -3,379 | -9,133 | -16,895 | -45,665 | -283,123 | -995,497 | -1,415,615 | -4,977,485 | -30,860,407 | -154,302,035 |
