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 150,106,177, 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 | 150,106,177 | |
| -1 | -150,106,177 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,106,177.
Example:
1 x 150,106,177 = 150,106,177
and
-1 x -150,106,177 = 150,106,177
Notice both answers equal 150,106,177
With that explanation out of the way, let's continue. Next, we take the number 150,106,177 and divide it by 2:
150,106,177 ÷ 2 = 75,053,088.5
If the quotient is a whole number, then 2 and 75,053,088.5 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 | 150,106,177 | |
| -1 | -150,106,177 |
Now, we try dividing 150,106,177 by 3:
150,106,177 ÷ 3 = 50,035,392.3333
If the quotient is a whole number, then 3 and 50,035,392.3333 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 | 150,106,177 | |
| -1 | -150,106,177 |
Let's try dividing by 4:
150,106,177 ÷ 4 = 37,526,544.25
If the quotient is a whole number, then 4 and 37,526,544.25 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 | 150,106,177 | |
| -1 | 150,106,177 |
If you did it right, you will end up with this table:
| 1 | 13 | 61 | 73 | 793 | 949 | 2,593 | 4,453 | 33,709 | 57,889 | 158,173 | 189,289 | 2,056,249 | 2,460,757 | 11,546,629 | 150,106,177 |
| -1 | -13 | -61 | -73 | -793 | -949 | -2,593 | -4,453 | -33,709 | -57,889 | -158,173 | -189,289 | -2,056,249 | -2,460,757 | -11,546,629 | -150,106,177 |
