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 151,434,409, 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 | 151,434,409 | |
| -1 | -151,434,409 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 151,434,409.
Example:
1 x 151,434,409 = 151,434,409
and
-1 x -151,434,409 = 151,434,409
Notice both answers equal 151,434,409
With that explanation out of the way, let's continue. Next, we take the number 151,434,409 and divide it by 2:
151,434,409 ÷ 2 = 75,717,204.5
If the quotient is a whole number, then 2 and 75,717,204.5 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 | 151,434,409 | |
| -1 | -151,434,409 |
Now, we try dividing 151,434,409 by 3:
151,434,409 ÷ 3 = 50,478,136.3333
If the quotient is a whole number, then 3 and 50,478,136.3333 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 | 151,434,409 | |
| -1 | -151,434,409 |
Let's try dividing by 4:
151,434,409 ÷ 4 = 37,858,602.25
If the quotient is a whole number, then 4 and 37,858,602.25 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 | 151,434,409 | |
| -1 | 151,434,409 |
If you did it right, you will end up with this table:
| 1 | 7 | 53 | 71 | 371 | 497 | 3,763 | 5,749 | 26,341 | 40,243 | 304,697 | 408,179 | 2,132,879 | 2,857,253 | 21,633,487 | 151,434,409 |
| -1 | -7 | -53 | -71 | -371 | -497 | -3,763 | -5,749 | -26,341 | -40,243 | -304,697 | -408,179 | -2,132,879 | -2,857,253 | -21,633,487 | -151,434,409 |
