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 154,777,723, 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 | 154,777,723 | |
-1 | -154,777,723 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,777,723.
Example:
1 x 154,777,723 = 154,777,723
and
-1 x -154,777,723 = 154,777,723
Notice both answers equal 154,777,723
With that explanation out of the way, let's continue. Next, we take the number 154,777,723 and divide it by 2:
154,777,723 ÷ 2 = 77,388,861.5
If the quotient is a whole number, then 2 and 77,388,861.5 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 | 154,777,723 | |
-1 | -154,777,723 |
Now, we try dividing 154,777,723 by 3:
154,777,723 ÷ 3 = 51,592,574.3333
If the quotient is a whole number, then 3 and 51,592,574.3333 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 | 154,777,723 | |
-1 | -154,777,723 |
Let's try dividing by 4:
154,777,723 ÷ 4 = 38,694,430.75
If the quotient is a whole number, then 4 and 38,694,430.75 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 | 154,777,723 | |
-1 | 154,777,723 |
If you did it right, you will end up with this table:
1 | 2,053 | 75,391 | 154,777,723 |
-1 | -2,053 | -75,391 | -154,777,723 |
