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 153,662,075, 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 | 153,662,075 | |
| -1 | -153,662,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,662,075.
Example:
1 x 153,662,075 = 153,662,075
and
-1 x -153,662,075 = 153,662,075
Notice both answers equal 153,662,075
With that explanation out of the way, let's continue. Next, we take the number 153,662,075 and divide it by 2:
153,662,075 ÷ 2 = 76,831,037.5
If the quotient is a whole number, then 2 and 76,831,037.5 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 | 153,662,075 | |
| -1 | -153,662,075 |
Now, we try dividing 153,662,075 by 3:
153,662,075 ÷ 3 = 51,220,691.6667
If the quotient is a whole number, then 3 and 51,220,691.6667 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 | 153,662,075 | |
| -1 | -153,662,075 |
Let's try dividing by 4:
153,662,075 ÷ 4 = 38,415,518.75
If the quotient is a whole number, then 4 and 38,415,518.75 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 | 153,662,075 | |
| -1 | 153,662,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 677 | 1,297 | 3,385 | 4,739 | 6,485 | 9,079 | 16,925 | 23,695 | 32,425 | 45,395 | 118,475 | 226,975 | 878,069 | 4,390,345 | 6,146,483 | 21,951,725 | 30,732,415 | 153,662,075 |
| -1 | -5 | -7 | -25 | -35 | -175 | -677 | -1,297 | -3,385 | -4,739 | -6,485 | -9,079 | -16,925 | -23,695 | -32,425 | -45,395 | -118,475 | -226,975 | -878,069 | -4,390,345 | -6,146,483 | -21,951,725 | -30,732,415 | -153,662,075 |
