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 150,542,455, 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 | 150,542,455 | |
| -1 | -150,542,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,542,455.
Example:
1 x 150,542,455 = 150,542,455
and
-1 x -150,542,455 = 150,542,455
Notice both answers equal 150,542,455
With that explanation out of the way, let's continue. Next, we take the number 150,542,455 and divide it by 2:
150,542,455 ÷ 2 = 75,271,227.5
If the quotient is a whole number, then 2 and 75,271,227.5 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 | 150,542,455 | |
| -1 | -150,542,455 |
Now, we try dividing 150,542,455 by 3:
150,542,455 ÷ 3 = 50,180,818.3333
If the quotient is a whole number, then 3 and 50,180,818.3333 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 | 150,542,455 | |
| -1 | -150,542,455 |
Let's try dividing by 4:
150,542,455 ÷ 4 = 37,635,613.75
If the quotient is a whole number, then 4 and 37,635,613.75 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 | 150,542,455 | |
| -1 | 150,542,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 49 | 185 | 245 | 259 | 1,295 | 1,813 | 9,065 | 16,607 | 83,035 | 116,249 | 581,245 | 614,459 | 813,743 | 3,072,295 | 4,068,715 | 4,301,213 | 21,506,065 | 30,108,491 | 150,542,455 |
| -1 | -5 | -7 | -35 | -37 | -49 | -185 | -245 | -259 | -1,295 | -1,813 | -9,065 | -16,607 | -83,035 | -116,249 | -581,245 | -614,459 | -813,743 | -3,072,295 | -4,068,715 | -4,301,213 | -21,506,065 | -30,108,491 | -150,542,455 |
