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 155,141,119, 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 | 155,141,119 | |
| -1 | -155,141,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 155,141,119.
Example:
1 x 155,141,119 = 155,141,119
and
-1 x -155,141,119 = 155,141,119
Notice both answers equal 155,141,119
With that explanation out of the way, let's continue. Next, we take the number 155,141,119 and divide it by 2:
155,141,119 ÷ 2 = 77,570,559.5
If the quotient is a whole number, then 2 and 77,570,559.5 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 | 155,141,119 | |
| -1 | -155,141,119 |
Now, we try dividing 155,141,119 by 3:
155,141,119 ÷ 3 = 51,713,706.3333
If the quotient is a whole number, then 3 and 51,713,706.3333 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 | 155,141,119 | |
| -1 | -155,141,119 |
Let's try dividing by 4:
155,141,119 ÷ 4 = 38,785,279.75
If the quotient is a whole number, then 4 and 38,785,279.75 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 | 155,141,119 | |
| -1 | 155,141,119 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 107 | 301 | 749 | 4,601 | 4,817 | 32,207 | 33,719 | 207,131 | 515,419 | 1,449,917 | 3,607,933 | 22,163,017 | 155,141,119 |
| -1 | -7 | -43 | -107 | -301 | -749 | -4,601 | -4,817 | -32,207 | -33,719 | -207,131 | -515,419 | -1,449,917 | -3,607,933 | -22,163,017 | -155,141,119 |
