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 154,763,735, 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 | 154,763,735 | |
| -1 | -154,763,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 154,763,735.
Example:
1 x 154,763,735 = 154,763,735
and
-1 x -154,763,735 = 154,763,735
Notice both answers equal 154,763,735
With that explanation out of the way, let's continue. Next, we take the number 154,763,735 and divide it by 2:
154,763,735 ÷ 2 = 77,381,867.5
If the quotient is a whole number, then 2 and 77,381,867.5 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 | 154,763,735 | |
| -1 | -154,763,735 |
Now, we try dividing 154,763,735 by 3:
154,763,735 ÷ 3 = 51,587,911.6667
If the quotient is a whole number, then 3 and 51,587,911.6667 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 | 154,763,735 | |
| -1 | -154,763,735 |
Let's try dividing by 4:
154,763,735 ÷ 4 = 38,690,933.75
If the quotient is a whole number, then 4 and 38,690,933.75 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 | 154,763,735 | |
| -1 | 154,763,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 347 | 1,735 | 2,429 | 12,145 | 12,743 | 63,715 | 89,201 | 446,005 | 4,421,821 | 22,109,105 | 30,952,747 | 154,763,735 |
| -1 | -5 | -7 | -35 | -347 | -1,735 | -2,429 | -12,145 | -12,743 | -63,715 | -89,201 | -446,005 | -4,421,821 | -22,109,105 | -30,952,747 | -154,763,735 |
