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 150,611,705, 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 | 150,611,705 | |
| -1 | -150,611,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,611,705.
Example:
1 x 150,611,705 = 150,611,705
and
-1 x -150,611,705 = 150,611,705
Notice both answers equal 150,611,705
With that explanation out of the way, let's continue. Next, we take the number 150,611,705 and divide it by 2:
150,611,705 ÷ 2 = 75,305,852.5
If the quotient is a whole number, then 2 and 75,305,852.5 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 | 150,611,705 | |
| -1 | -150,611,705 |
Now, we try dividing 150,611,705 by 3:
150,611,705 ÷ 3 = 50,203,901.6667
If the quotient is a whole number, then 3 and 50,203,901.6667 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 | 150,611,705 | |
| -1 | -150,611,705 |
Let's try dividing by 4:
150,611,705 ÷ 4 = 37,652,926.25
If the quotient is a whole number, then 4 and 37,652,926.25 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 | 150,611,705 | |
| -1 | 150,611,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 101 | 115 | 505 | 2,323 | 11,615 | 12,967 | 64,835 | 298,241 | 1,309,667 | 1,491,205 | 6,548,335 | 30,122,341 | 150,611,705 |
| -1 | -5 | -23 | -101 | -115 | -505 | -2,323 | -11,615 | -12,967 | -64,835 | -298,241 | -1,309,667 | -1,491,205 | -6,548,335 | -30,122,341 | -150,611,705 |
