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 151,041,065, 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 | 151,041,065 | |
| -1 | -151,041,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,041,065.
Example:
1 x 151,041,065 = 151,041,065
and
-1 x -151,041,065 = 151,041,065
Notice both answers equal 151,041,065
With that explanation out of the way, let's continue. Next, we take the number 151,041,065 and divide it by 2:
151,041,065 ÷ 2 = 75,520,532.5
If the quotient is a whole number, then 2 and 75,520,532.5 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 | 151,041,065 | |
| -1 | -151,041,065 |
Now, we try dividing 151,041,065 by 3:
151,041,065 ÷ 3 = 50,347,021.6667
If the quotient is a whole number, then 3 and 50,347,021.6667 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 | 151,041,065 | |
| -1 | -151,041,065 |
Let's try dividing by 4:
151,041,065 ÷ 4 = 37,760,266.25
If the quotient is a whole number, then 4 and 37,760,266.25 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 | 151,041,065 | |
| -1 | 151,041,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 157 | 785 | 1,099 | 5,495 | 27,487 | 137,435 | 192,409 | 962,045 | 4,315,459 | 21,577,295 | 30,208,213 | 151,041,065 |
| -1 | -5 | -7 | -35 | -157 | -785 | -1,099 | -5,495 | -27,487 | -137,435 | -192,409 | -962,045 | -4,315,459 | -21,577,295 | -30,208,213 | -151,041,065 |
