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 152,727,199, 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 | 152,727,199 | |
| -1 | -152,727,199 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 152,727,199.
Example:
1 x 152,727,199 = 152,727,199
and
-1 x -152,727,199 = 152,727,199
Notice both answers equal 152,727,199
With that explanation out of the way, let's continue. Next, we take the number 152,727,199 and divide it by 2:
152,727,199 ÷ 2 = 76,363,599.5
If the quotient is a whole number, then 2 and 76,363,599.5 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 | 152,727,199 | |
| -1 | -152,727,199 |
Now, we try dividing 152,727,199 by 3:
152,727,199 ÷ 3 = 50,909,066.3333
If the quotient is a whole number, then 3 and 50,909,066.3333 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 | 152,727,199 | |
| -1 | -152,727,199 |
Let's try dividing by 4:
152,727,199 ÷ 4 = 38,181,799.75
If the quotient is a whole number, then 4 and 38,181,799.75 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 | 152,727,199 | |
| -1 | 152,727,199 |
If you did it right, you will end up with this table:
| 1 | 23 | 107 | 229 | 271 | 2,461 | 5,267 | 6,233 | 24,503 | 28,997 | 62,059 | 563,569 | 666,931 | 1,427,357 | 6,640,313 | 152,727,199 |
| -1 | -23 | -107 | -229 | -271 | -2,461 | -5,267 | -6,233 | -24,503 | -28,997 | -62,059 | -563,569 | -666,931 | -1,427,357 | -6,640,313 | -152,727,199 |
