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 150,488,555, 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 | 150,488,555 | |
| -1 | -150,488,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,488,555.
Example:
1 x 150,488,555 = 150,488,555
and
-1 x -150,488,555 = 150,488,555
Notice both answers equal 150,488,555
With that explanation out of the way, let's continue. Next, we take the number 150,488,555 and divide it by 2:
150,488,555 ÷ 2 = 75,244,277.5
If the quotient is a whole number, then 2 and 75,244,277.5 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 | 150,488,555 | |
| -1 | -150,488,555 |
Now, we try dividing 150,488,555 by 3:
150,488,555 ÷ 3 = 50,162,851.6667
If the quotient is a whole number, then 3 and 50,162,851.6667 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 | 150,488,555 | |
| -1 | -150,488,555 |
Let's try dividing by 4:
150,488,555 ÷ 4 = 37,622,138.75
If the quotient is a whole number, then 4 and 37,622,138.75 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 | 150,488,555 | |
| -1 | 150,488,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 421 | 1,459 | 2,105 | 2,947 | 7,295 | 10,213 | 14,735 | 20,629 | 51,065 | 71,491 | 103,145 | 357,455 | 614,239 | 3,071,195 | 4,299,673 | 21,498,365 | 30,097,711 | 150,488,555 |
| -1 | -5 | -7 | -35 | -49 | -245 | -421 | -1,459 | -2,105 | -2,947 | -7,295 | -10,213 | -14,735 | -20,629 | -51,065 | -71,491 | -103,145 | -357,455 | -614,239 | -3,071,195 | -4,299,673 | -21,498,365 | -30,097,711 | -150,488,555 |
