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 150,146,633, 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 | 150,146,633 | |
| -1 | -150,146,633 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,146,633.
Example:
1 x 150,146,633 = 150,146,633
and
-1 x -150,146,633 = 150,146,633
Notice both answers equal 150,146,633
With that explanation out of the way, let's continue. Next, we take the number 150,146,633 and divide it by 2:
150,146,633 ÷ 2 = 75,073,316.5
If the quotient is a whole number, then 2 and 75,073,316.5 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 | 150,146,633 | |
| -1 | -150,146,633 |
Now, we try dividing 150,146,633 by 3:
150,146,633 ÷ 3 = 50,048,877.6667
If the quotient is a whole number, then 3 and 50,048,877.6667 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 | 150,146,633 | |
| -1 | -150,146,633 |
Let's try dividing by 4:
150,146,633 ÷ 4 = 37,536,658.25
If the quotient is a whole number, then 4 and 37,536,658.25 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 | 150,146,633 | |
| -1 | 150,146,633 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 41 | 49 | 91 | 287 | 533 | 637 | 2,009 | 3,731 | 5,749 | 26,117 | 40,243 | 74,737 | 235,709 | 281,701 | 523,159 | 1,649,963 | 3,064,217 | 3,662,113 | 11,549,741 | 21,449,519 | 150,146,633 |
| -1 | -7 | -13 | -41 | -49 | -91 | -287 | -533 | -637 | -2,009 | -3,731 | -5,749 | -26,117 | -40,243 | -74,737 | -235,709 | -281,701 | -523,159 | -1,649,963 | -3,064,217 | -3,662,113 | -11,549,741 | -21,449,519 | -150,146,633 |
