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 151,404,533, 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 | 151,404,533 | |
| -1 | -151,404,533 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,404,533.
Example:
1 x 151,404,533 = 151,404,533
and
-1 x -151,404,533 = 151,404,533
Notice both answers equal 151,404,533
With that explanation out of the way, let's continue. Next, we take the number 151,404,533 and divide it by 2:
151,404,533 ÷ 2 = 75,702,266.5
If the quotient is a whole number, then 2 and 75,702,266.5 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 | 151,404,533 | |
| -1 | -151,404,533 |
Now, we try dividing 151,404,533 by 3:
151,404,533 ÷ 3 = 50,468,177.6667
If the quotient is a whole number, then 3 and 50,468,177.6667 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 | 151,404,533 | |
| -1 | -151,404,533 |
Let's try dividing by 4:
151,404,533 ÷ 4 = 37,851,133.25
If the quotient is a whole number, then 4 and 37,851,133.25 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 | 151,404,533 | |
| -1 | 151,404,533 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 83 | 119 | 581 | 1,411 | 9,877 | 15,329 | 107,303 | 260,593 | 1,272,307 | 1,824,151 | 8,906,149 | 21,629,219 | 151,404,533 |
| -1 | -7 | -17 | -83 | -119 | -581 | -1,411 | -9,877 | -15,329 | -107,303 | -260,593 | -1,272,307 | -1,824,151 | -8,906,149 | -21,629,219 | -151,404,533 |
