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 151,304,845, 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 | 151,304,845 | |
| -1 | -151,304,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,304,845.
Example:
1 x 151,304,845 = 151,304,845
and
-1 x -151,304,845 = 151,304,845
Notice both answers equal 151,304,845
With that explanation out of the way, let's continue. Next, we take the number 151,304,845 and divide it by 2:
151,304,845 ÷ 2 = 75,652,422.5
If the quotient is a whole number, then 2 and 75,652,422.5 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 | 151,304,845 | |
| -1 | -151,304,845 |
Now, we try dividing 151,304,845 by 3:
151,304,845 ÷ 3 = 50,434,948.3333
If the quotient is a whole number, then 3 and 50,434,948.3333 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 | 151,304,845 | |
| -1 | -151,304,845 |
Let's try dividing by 4:
151,304,845 ÷ 4 = 37,826,211.25
If the quotient is a whole number, then 4 and 37,826,211.25 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 | 151,304,845 | |
| -1 | 151,304,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 641 | 2,777 | 3,205 | 10,897 | 13,885 | 47,209 | 54,485 | 236,045 | 1,780,057 | 8,900,285 | 30,260,969 | 151,304,845 |
| -1 | -5 | -17 | -85 | -641 | -2,777 | -3,205 | -10,897 | -13,885 | -47,209 | -54,485 | -236,045 | -1,780,057 | -8,900,285 | -30,260,969 | -151,304,845 |
