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 158,407,631, 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 | 158,407,631 | |
-1 | -158,407,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 158,407,631.
Example:
1 x 158,407,631 = 158,407,631
and
-1 x -158,407,631 = 158,407,631
Notice both answers equal 158,407,631
With that explanation out of the way, let's continue. Next, we take the number 158,407,631 and divide it by 2:
158,407,631 ÷ 2 = 79,203,815.5
If the quotient is a whole number, then 2 and 79,203,815.5 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 | 158,407,631 | |
-1 | -158,407,631 |
Now, we try dividing 158,407,631 by 3:
158,407,631 ÷ 3 = 52,802,543.6667
If the quotient is a whole number, then 3 and 52,802,543.6667 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 | 158,407,631 | |
-1 | -158,407,631 |
Let's try dividing by 4:
158,407,631 ÷ 4 = 39,601,907.75
If the quotient is a whole number, then 4 and 39,601,907.75 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 | 158,407,631 | |
-1 | 158,407,631 |
If you did it right, you will end up with this table:
1 | 67 | 2,364,293 | 158,407,631 |
-1 | -67 | -2,364,293 | -158,407,631 |
