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 154,624,571, 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 | 154,624,571 | |
| -1 | -154,624,571 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,624,571.
Example:
1 x 154,624,571 = 154,624,571
and
-1 x -154,624,571 = 154,624,571
Notice both answers equal 154,624,571
With that explanation out of the way, let's continue. Next, we take the number 154,624,571 and divide it by 2:
154,624,571 ÷ 2 = 77,312,285.5
If the quotient is a whole number, then 2 and 77,312,285.5 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 | 154,624,571 | |
| -1 | -154,624,571 |
Now, we try dividing 154,624,571 by 3:
154,624,571 ÷ 3 = 51,541,523.6667
If the quotient is a whole number, then 3 and 51,541,523.6667 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 | 154,624,571 | |
| -1 | -154,624,571 |
Let's try dividing by 4:
154,624,571 ÷ 4 = 38,656,142.75
If the quotient is a whole number, then 4 and 38,656,142.75 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 | 154,624,571 | |
| -1 | 154,624,571 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 163 | 697 | 1,361 | 2,771 | 6,683 | 23,137 | 55,801 | 113,611 | 221,843 | 948,617 | 3,771,331 | 9,095,563 | 154,624,571 |
| -1 | -17 | -41 | -163 | -697 | -1,361 | -2,771 | -6,683 | -23,137 | -55,801 | -113,611 | -221,843 | -948,617 | -3,771,331 | -9,095,563 | -154,624,571 |
