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 154,310,143, 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 | 154,310,143 | |
-1 | -154,310,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,310,143.
Example:
1 x 154,310,143 = 154,310,143
and
-1 x -154,310,143 = 154,310,143
Notice both answers equal 154,310,143
With that explanation out of the way, let's continue. Next, we take the number 154,310,143 and divide it by 2:
154,310,143 ÷ 2 = 77,155,071.5
If the quotient is a whole number, then 2 and 77,155,071.5 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 | 154,310,143 | |
-1 | -154,310,143 |
Now, we try dividing 154,310,143 by 3:
154,310,143 ÷ 3 = 51,436,714.3333
If the quotient is a whole number, then 3 and 51,436,714.3333 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 | 154,310,143 | |
-1 | -154,310,143 |
Let's try dividing by 4:
154,310,143 ÷ 4 = 38,577,535.75
If the quotient is a whole number, then 4 and 38,577,535.75 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 | 154,310,143 | |
-1 | 154,310,143 |
If you did it right, you will end up with this table:
1 | 13 | 11,870,011 | 154,310,143 |
-1 | -13 | -11,870,011 | -154,310,143 |
