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 155,006,075, 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 | 155,006,075 | |
| -1 | -155,006,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 155,006,075.
Example:
1 x 155,006,075 = 155,006,075
and
-1 x -155,006,075 = 155,006,075
Notice both answers equal 155,006,075
With that explanation out of the way, let's continue. Next, we take the number 155,006,075 and divide it by 2:
155,006,075 ÷ 2 = 77,503,037.5
If the quotient is a whole number, then 2 and 77,503,037.5 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 | 155,006,075 | |
| -1 | -155,006,075 |
Now, we try dividing 155,006,075 by 3:
155,006,075 ÷ 3 = 51,668,691.6667
If the quotient is a whole number, then 3 and 51,668,691.6667 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 | 155,006,075 | |
| -1 | -155,006,075 |
Let's try dividing by 4:
155,006,075 ÷ 4 = 38,751,518.75
If the quotient is a whole number, then 4 and 38,751,518.75 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 | 155,006,075 | |
| -1 | 155,006,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 199 | 995 | 1,393 | 4,451 | 4,975 | 6,965 | 22,255 | 31,157 | 34,825 | 111,275 | 155,785 | 778,925 | 885,749 | 4,428,745 | 6,200,243 | 22,143,725 | 31,001,215 | 155,006,075 |
| -1 | -5 | -7 | -25 | -35 | -175 | -199 | -995 | -1,393 | -4,451 | -4,975 | -6,965 | -22,255 | -31,157 | -34,825 | -111,275 | -155,785 | -778,925 | -885,749 | -4,428,745 | -6,200,243 | -22,143,725 | -31,001,215 | -155,006,075 |
