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 155,440,043, 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 | 155,440,043 | |
| -1 | -155,440,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 155,440,043.
Example:
1 x 155,440,043 = 155,440,043
and
-1 x -155,440,043 = 155,440,043
Notice both answers equal 155,440,043
With that explanation out of the way, let's continue. Next, we take the number 155,440,043 and divide it by 2:
155,440,043 ÷ 2 = 77,720,021.5
If the quotient is a whole number, then 2 and 77,720,021.5 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 | 155,440,043 | |
| -1 | -155,440,043 |
Now, we try dividing 155,440,043 by 3:
155,440,043 ÷ 3 = 51,813,347.6667
If the quotient is a whole number, then 3 and 51,813,347.6667 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 | 155,440,043 | |
| -1 | -155,440,043 |
Let's try dividing by 4:
155,440,043 ÷ 4 = 38,860,010.75
If the quotient is a whole number, then 4 and 38,860,010.75 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 | 155,440,043 | |
| -1 | 155,440,043 |
If you did it right, you will end up with this table:
| 1 | 11 | 53 | 59 | 583 | 649 | 3,127 | 4,519 | 34,397 | 49,709 | 239,507 | 266,621 | 2,634,577 | 2,932,831 | 14,130,913 | 155,440,043 |
| -1 | -11 | -53 | -59 | -583 | -649 | -3,127 | -4,519 | -34,397 | -49,709 | -239,507 | -266,621 | -2,634,577 | -2,932,831 | -14,130,913 | -155,440,043 |
