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 150,235,525, 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 | 150,235,525 | |
| -1 | -150,235,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,235,525.
Example:
1 x 150,235,525 = 150,235,525
and
-1 x -150,235,525 = 150,235,525
Notice both answers equal 150,235,525
With that explanation out of the way, let's continue. Next, we take the number 150,235,525 and divide it by 2:
150,235,525 ÷ 2 = 75,117,762.5
If the quotient is a whole number, then 2 and 75,117,762.5 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 | 150,235,525 | |
| -1 | -150,235,525 |
Now, we try dividing 150,235,525 by 3:
150,235,525 ÷ 3 = 50,078,508.3333
If the quotient is a whole number, then 3 and 50,078,508.3333 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 | 150,235,525 | |
| -1 | -150,235,525 |
Let's try dividing by 4:
150,235,525 ÷ 4 = 37,558,881.25
If the quotient is a whole number, then 4 and 37,558,881.25 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 | 150,235,525 | |
| -1 | 150,235,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 275 | 659 | 829 | 3,295 | 4,145 | 7,249 | 9,119 | 16,475 | 20,725 | 36,245 | 45,595 | 181,225 | 227,975 | 546,311 | 2,731,555 | 6,009,421 | 13,657,775 | 30,047,105 | 150,235,525 |
| -1 | -5 | -11 | -25 | -55 | -275 | -659 | -829 | -3,295 | -4,145 | -7,249 | -9,119 | -16,475 | -20,725 | -36,245 | -45,595 | -181,225 | -227,975 | -546,311 | -2,731,555 | -6,009,421 | -13,657,775 | -30,047,105 | -150,235,525 |
