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 155,704,075, 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 | 155,704,075 | |
| -1 | -155,704,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 155,704,075.
Example:
1 x 155,704,075 = 155,704,075
and
-1 x -155,704,075 = 155,704,075
Notice both answers equal 155,704,075
With that explanation out of the way, let's continue. Next, we take the number 155,704,075 and divide it by 2:
155,704,075 ÷ 2 = 77,852,037.5
If the quotient is a whole number, then 2 and 77,852,037.5 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 | 155,704,075 | |
| -1 | -155,704,075 |
Now, we try dividing 155,704,075 by 3:
155,704,075 ÷ 3 = 51,901,358.3333
If the quotient is a whole number, then 3 and 51,901,358.3333 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 | 155,704,075 | |
| -1 | -155,704,075 |
Let's try dividing by 4:
155,704,075 ÷ 4 = 38,926,018.75
If the quotient is a whole number, then 4 and 38,926,018.75 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 | 155,704,075 | |
| -1 | 155,704,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 215 | 241 | 601 | 1,075 | 1,205 | 3,005 | 6,025 | 10,363 | 15,025 | 25,843 | 51,815 | 129,215 | 144,841 | 259,075 | 646,075 | 724,205 | 3,621,025 | 6,228,163 | 31,140,815 | 155,704,075 |
| -1 | -5 | -25 | -43 | -215 | -241 | -601 | -1,075 | -1,205 | -3,005 | -6,025 | -10,363 | -15,025 | -25,843 | -51,815 | -129,215 | -144,841 | -259,075 | -646,075 | -724,205 | -3,621,025 | -6,228,163 | -31,140,815 | -155,704,075 |
