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 152,604,563, 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 | 152,604,563 | |
| -1 | -152,604,563 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,604,563.
Example:
1 x 152,604,563 = 152,604,563
and
-1 x -152,604,563 = 152,604,563
Notice both answers equal 152,604,563
With that explanation out of the way, let's continue. Next, we take the number 152,604,563 and divide it by 2:
152,604,563 ÷ 2 = 76,302,281.5
If the quotient is a whole number, then 2 and 76,302,281.5 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 | 152,604,563 | |
| -1 | -152,604,563 |
Now, we try dividing 152,604,563 by 3:
152,604,563 ÷ 3 = 50,868,187.6667
If the quotient is a whole number, then 3 and 50,868,187.6667 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 | 152,604,563 | |
| -1 | -152,604,563 |
Let's try dividing by 4:
152,604,563 ÷ 4 = 38,151,140.75
If the quotient is a whole number, then 4 and 38,151,140.75 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 | 152,604,563 | |
| -1 | 152,604,563 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 277 | 391 | 1,409 | 4,709 | 6,371 | 23,953 | 32,407 | 108,307 | 390,293 | 550,919 | 6,634,981 | 8,976,739 | 152,604,563 |
| -1 | -17 | -23 | -277 | -391 | -1,409 | -4,709 | -6,371 | -23,953 | -32,407 | -108,307 | -390,293 | -550,919 | -6,634,981 | -8,976,739 | -152,604,563 |
