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 150,420,029, 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 | 150,420,029 | |
| -1 | -150,420,029 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,420,029.
Example:
1 x 150,420,029 = 150,420,029
and
-1 x -150,420,029 = 150,420,029
Notice both answers equal 150,420,029
With that explanation out of the way, let's continue. Next, we take the number 150,420,029 and divide it by 2:
150,420,029 ÷ 2 = 75,210,014.5
If the quotient is a whole number, then 2 and 75,210,014.5 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 | 150,420,029 | |
| -1 | -150,420,029 |
Now, we try dividing 150,420,029 by 3:
150,420,029 ÷ 3 = 50,140,009.6667
If the quotient is a whole number, then 3 and 50,140,009.6667 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 | 150,420,029 | |
| -1 | -150,420,029 |
Let's try dividing by 4:
150,420,029 ÷ 4 = 37,605,007.25
If the quotient is a whole number, then 4 and 37,605,007.25 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 | 150,420,029 | |
| -1 | 150,420,029 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 79 | 527 | 1,343 | 2,449 | 3,613 | 41,633 | 61,421 | 112,003 | 285,427 | 1,904,051 | 4,852,259 | 8,848,237 | 150,420,029 |
| -1 | -17 | -31 | -79 | -527 | -1,343 | -2,449 | -3,613 | -41,633 | -61,421 | -112,003 | -285,427 | -1,904,051 | -4,852,259 | -8,848,237 | -150,420,029 |
