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 152,302,585, 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 | 152,302,585 | |
| -1 | -152,302,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,302,585.
Example:
1 x 152,302,585 = 152,302,585
and
-1 x -152,302,585 = 152,302,585
Notice both answers equal 152,302,585
With that explanation out of the way, let's continue. Next, we take the number 152,302,585 and divide it by 2:
152,302,585 ÷ 2 = 76,151,292.5
If the quotient is a whole number, then 2 and 76,151,292.5 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 | 152,302,585 | |
| -1 | -152,302,585 |
Now, we try dividing 152,302,585 by 3:
152,302,585 ÷ 3 = 50,767,528.3333
If the quotient is a whole number, then 3 and 50,767,528.3333 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 | 152,302,585 | |
| -1 | -152,302,585 |
Let's try dividing by 4:
152,302,585 ÷ 4 = 38,075,646.25
If the quotient is a whole number, then 4 and 38,075,646.25 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 | 152,302,585 | |
| -1 | 152,302,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 149 | 445 | 745 | 2,297 | 11,485 | 13,261 | 66,305 | 204,433 | 342,253 | 1,022,165 | 1,711,265 | 30,460,517 | 152,302,585 |
| -1 | -5 | -89 | -149 | -445 | -745 | -2,297 | -11,485 | -13,261 | -66,305 | -204,433 | -342,253 | -1,022,165 | -1,711,265 | -30,460,517 | -152,302,585 |
