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 151,343,101, 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 | 151,343,101 | |
| -1 | -151,343,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,343,101.
Example:
1 x 151,343,101 = 151,343,101
and
-1 x -151,343,101 = 151,343,101
Notice both answers equal 151,343,101
With that explanation out of the way, let's continue. Next, we take the number 151,343,101 and divide it by 2:
151,343,101 ÷ 2 = 75,671,550.5
If the quotient is a whole number, then 2 and 75,671,550.5 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 | 151,343,101 | |
| -1 | -151,343,101 |
Now, we try dividing 151,343,101 by 3:
151,343,101 ÷ 3 = 50,447,700.3333
If the quotient is a whole number, then 3 and 50,447,700.3333 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 | 151,343,101 | |
| -1 | -151,343,101 |
Let's try dividing by 4:
151,343,101 ÷ 4 = 37,835,775.25
If the quotient is a whole number, then 4 and 37,835,775.25 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 | 151,343,101 | |
| -1 | 151,343,101 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 43 | 91 | 301 | 559 | 3,913 | 38,677 | 270,739 | 502,801 | 1,663,111 | 3,519,607 | 11,641,777 | 21,620,443 | 151,343,101 |
| -1 | -7 | -13 | -43 | -91 | -301 | -559 | -3,913 | -38,677 | -270,739 | -502,801 | -1,663,111 | -3,519,607 | -11,641,777 | -21,620,443 | -151,343,101 |
