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 149,124,755, 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 | 149,124,755 | |
| -1 | -149,124,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 149,124,755.
Example:
1 x 149,124,755 = 149,124,755
and
-1 x -149,124,755 = 149,124,755
Notice both answers equal 149,124,755
With that explanation out of the way, let's continue. Next, we take the number 149,124,755 and divide it by 2:
149,124,755 ÷ 2 = 74,562,377.5
If the quotient is a whole number, then 2 and 74,562,377.5 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 | 149,124,755 | |
| -1 | -149,124,755 |
Now, we try dividing 149,124,755 by 3:
149,124,755 ÷ 3 = 49,708,251.6667
If the quotient is a whole number, then 3 and 49,708,251.6667 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 | 149,124,755 | |
| -1 | -149,124,755 |
Let's try dividing by 4:
149,124,755 ÷ 4 = 37,281,188.75
If the quotient is a whole number, then 4 and 37,281,188.75 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 | 149,124,755 | |
| -1 | 149,124,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 65 | 115 | 169 | 299 | 845 | 1,495 | 3,887 | 7,673 | 19,435 | 38,365 | 99,749 | 176,479 | 498,745 | 882,395 | 1,296,737 | 2,294,227 | 6,483,685 | 11,471,135 | 29,824,951 | 149,124,755 |
| -1 | -5 | -13 | -23 | -65 | -115 | -169 | -299 | -845 | -1,495 | -3,887 | -7,673 | -19,435 | -38,365 | -99,749 | -176,479 | -498,745 | -882,395 | -1,296,737 | -2,294,227 | -6,483,685 | -11,471,135 | -29,824,951 | -149,124,755 |
