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 151,500,503, 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 | 151,500,503 | |
| -1 | -151,500,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,500,503.
Example:
1 x 151,500,503 = 151,500,503
and
-1 x -151,500,503 = 151,500,503
Notice both answers equal 151,500,503
With that explanation out of the way, let's continue. Next, we take the number 151,500,503 and divide it by 2:
151,500,503 ÷ 2 = 75,750,251.5
If the quotient is a whole number, then 2 and 75,750,251.5 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 | 151,500,503 | |
| -1 | -151,500,503 |
Now, we try dividing 151,500,503 by 3:
151,500,503 ÷ 3 = 50,500,167.6667
If the quotient is a whole number, then 3 and 50,500,167.6667 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 | 151,500,503 | |
| -1 | -151,500,503 |
Let's try dividing by 4:
151,500,503 ÷ 4 = 37,875,125.75
If the quotient is a whole number, then 4 and 37,875,125.75 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 | 151,500,503 | |
| -1 | 151,500,503 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 49 | 77 | 217 | 341 | 539 | 1,519 | 2,387 | 9,067 | 16,709 | 63,469 | 99,737 | 281,077 | 444,283 | 698,159 | 1,967,539 | 3,091,847 | 4,887,113 | 13,772,773 | 21,642,929 | 151,500,503 |
| -1 | -7 | -11 | -31 | -49 | -77 | -217 | -341 | -539 | -1,519 | -2,387 | -9,067 | -16,709 | -63,469 | -99,737 | -281,077 | -444,283 | -698,159 | -1,967,539 | -3,091,847 | -4,887,113 | -13,772,773 | -21,642,929 | -151,500,503 |
