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 150,350,347, 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 | 150,350,347 | |
| -1 | -150,350,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,350,347.
Example:
1 x 150,350,347 = 150,350,347
and
-1 x -150,350,347 = 150,350,347
Notice both answers equal 150,350,347
With that explanation out of the way, let's continue. Next, we take the number 150,350,347 and divide it by 2:
150,350,347 ÷ 2 = 75,175,173.5
If the quotient is a whole number, then 2 and 75,175,173.5 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 | 150,350,347 | |
| -1 | -150,350,347 |
Now, we try dividing 150,350,347 by 3:
150,350,347 ÷ 3 = 50,116,782.3333
If the quotient is a whole number, then 3 and 50,116,782.3333 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 | 150,350,347 | |
| -1 | -150,350,347 |
Let's try dividing by 4:
150,350,347 ÷ 4 = 37,587,586.75
If the quotient is a whole number, then 4 and 37,587,586.75 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 | 150,350,347 | |
| -1 | 150,350,347 |
If you did it right, you will end up with this table:
| 1 | 7 | 53 | 127 | 371 | 889 | 3,191 | 6,731 | 22,337 | 47,117 | 169,123 | 405,257 | 1,183,861 | 2,836,799 | 21,478,621 | 150,350,347 |
| -1 | -7 | -53 | -127 | -371 | -889 | -3,191 | -6,731 | -22,337 | -47,117 | -169,123 | -405,257 | -1,183,861 | -2,836,799 | -21,478,621 | -150,350,347 |
