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 151,792,895, 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 | 151,792,895 | |
| -1 | -151,792,895 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,792,895.
Example:
1 x 151,792,895 = 151,792,895
and
-1 x -151,792,895 = 151,792,895
Notice both answers equal 151,792,895
With that explanation out of the way, let's continue. Next, we take the number 151,792,895 and divide it by 2:
151,792,895 ÷ 2 = 75,896,447.5
If the quotient is a whole number, then 2 and 75,896,447.5 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 | 151,792,895 | |
| -1 | -151,792,895 |
Now, we try dividing 151,792,895 by 3:
151,792,895 ÷ 3 = 50,597,631.6667
If the quotient is a whole number, then 3 and 50,597,631.6667 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 | 151,792,895 | |
| -1 | -151,792,895 |
Let's try dividing by 4:
151,792,895 ÷ 4 = 37,948,223.75
If the quotient is a whole number, then 4 and 37,948,223.75 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 | 151,792,895 | |
| -1 | 151,792,895 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 179 | 895 | 5,471 | 5,549 | 27,355 | 27,745 | 169,601 | 848,005 | 979,309 | 4,896,545 | 30,358,579 | 151,792,895 |
| -1 | -5 | -31 | -155 | -179 | -895 | -5,471 | -5,549 | -27,355 | -27,745 | -169,601 | -848,005 | -979,309 | -4,896,545 | -30,358,579 | -151,792,895 |
