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 150,420,445, 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 | 150,420,445 | |
| -1 | -150,420,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,420,445.
Example:
1 x 150,420,445 = 150,420,445
and
-1 x -150,420,445 = 150,420,445
Notice both answers equal 150,420,445
With that explanation out of the way, let's continue. Next, we take the number 150,420,445 and divide it by 2:
150,420,445 ÷ 2 = 75,210,222.5
If the quotient is a whole number, then 2 and 75,210,222.5 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 | 150,420,445 | |
| -1 | -150,420,445 |
Now, we try dividing 150,420,445 by 3:
150,420,445 ÷ 3 = 50,140,148.3333
If the quotient is a whole number, then 3 and 50,140,148.3333 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 | 150,420,445 | |
| -1 | -150,420,445 |
Let's try dividing by 4:
150,420,445 ÷ 4 = 37,605,111.25
If the quotient is a whole number, then 4 and 37,605,111.25 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 | 150,420,445 | |
| -1 | 150,420,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 49 | 235 | 245 | 329 | 1,645 | 2,303 | 11,515 | 13,063 | 65,315 | 91,441 | 457,205 | 613,961 | 640,087 | 3,069,805 | 3,200,435 | 4,297,727 | 21,488,635 | 30,084,089 | 150,420,445 |
| -1 | -5 | -7 | -35 | -47 | -49 | -235 | -245 | -329 | -1,645 | -2,303 | -11,515 | -13,063 | -65,315 | -91,441 | -457,205 | -613,961 | -640,087 | -3,069,805 | -3,200,435 | -4,297,727 | -21,488,635 | -30,084,089 | -150,420,445 |
