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 155,010,443, 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 | 155,010,443 | |
| -1 | -155,010,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 155,010,443.
Example:
1 x 155,010,443 = 155,010,443
and
-1 x -155,010,443 = 155,010,443
Notice both answers equal 155,010,443
With that explanation out of the way, let's continue. Next, we take the number 155,010,443 and divide it by 2:
155,010,443 ÷ 2 = 77,505,221.5
If the quotient is a whole number, then 2 and 77,505,221.5 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 | 155,010,443 | |
| -1 | -155,010,443 |
Now, we try dividing 155,010,443 by 3:
155,010,443 ÷ 3 = 51,670,147.6667
If the quotient is a whole number, then 3 and 51,670,147.6667 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 | 155,010,443 | |
| -1 | -155,010,443 |
Let's try dividing by 4:
155,010,443 ÷ 4 = 38,752,610.75
If the quotient is a whole number, then 4 and 38,752,610.75 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 | 155,010,443 | |
| -1 | 155,010,443 |
If you did it right, you will end up with this table:
| 1 | 7 | 191 | 269 | 431 | 1,337 | 1,883 | 3,017 | 51,379 | 82,321 | 115,939 | 359,653 | 576,247 | 811,573 | 22,144,349 | 155,010,443 |
| -1 | -7 | -191 | -269 | -431 | -1,337 | -1,883 | -3,017 | -51,379 | -82,321 | -115,939 | -359,653 | -576,247 | -811,573 | -22,144,349 | -155,010,443 |
