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 151,600,729, 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 | 151,600,729 | |
| -1 | -151,600,729 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,600,729.
Example:
1 x 151,600,729 = 151,600,729
and
-1 x -151,600,729 = 151,600,729
Notice both answers equal 151,600,729
With that explanation out of the way, let's continue. Next, we take the number 151,600,729 and divide it by 2:
151,600,729 ÷ 2 = 75,800,364.5
If the quotient is a whole number, then 2 and 75,800,364.5 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 | 151,600,729 | |
| -1 | -151,600,729 |
Now, we try dividing 151,600,729 by 3:
151,600,729 ÷ 3 = 50,533,576.3333
If the quotient is a whole number, then 3 and 50,533,576.3333 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 | 151,600,729 | |
| -1 | -151,600,729 |
Let's try dividing by 4:
151,600,729 ÷ 4 = 37,900,182.25
If the quotient is a whole number, then 4 and 37,900,182.25 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 | 151,600,729 | |
| -1 | 151,600,729 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 259 | 683 | 857 | 4,781 | 5,999 | 25,271 | 31,709 | 176,897 | 221,963 | 585,331 | 4,097,317 | 21,657,247 | 151,600,729 |
| -1 | -7 | -37 | -259 | -683 | -857 | -4,781 | -5,999 | -25,271 | -31,709 | -176,897 | -221,963 | -585,331 | -4,097,317 | -21,657,247 | -151,600,729 |
