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 153,127,075, 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 | 153,127,075 | |
| -1 | -153,127,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,127,075.
Example:
1 x 153,127,075 = 153,127,075
and
-1 x -153,127,075 = 153,127,075
Notice both answers equal 153,127,075
With that explanation out of the way, let's continue. Next, we take the number 153,127,075 and divide it by 2:
153,127,075 ÷ 2 = 76,563,537.5
If the quotient is a whole number, then 2 and 76,563,537.5 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 | 153,127,075 | |
| -1 | -153,127,075 |
Now, we try dividing 153,127,075 by 3:
153,127,075 ÷ 3 = 51,042,358.3333
If the quotient is a whole number, then 3 and 51,042,358.3333 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 | 153,127,075 | |
| -1 | -153,127,075 |
Let's try dividing by 4:
153,127,075 ÷ 4 = 38,281,768.75
If the quotient is a whole number, then 4 and 38,281,768.75 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 | 153,127,075 | |
| -1 | 153,127,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 127 | 425 | 635 | 2,159 | 2,837 | 3,175 | 10,795 | 14,185 | 48,229 | 53,975 | 70,925 | 241,145 | 360,299 | 1,205,725 | 1,801,495 | 6,125,083 | 9,007,475 | 30,625,415 | 153,127,075 |
| -1 | -5 | -17 | -25 | -85 | -127 | -425 | -635 | -2,159 | -2,837 | -3,175 | -10,795 | -14,185 | -48,229 | -53,975 | -70,925 | -241,145 | -360,299 | -1,205,725 | -1,801,495 | -6,125,083 | -9,007,475 | -30,625,415 | -153,127,075 |
