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 153,434,255, 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 | 153,434,255 | |
| -1 | -153,434,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 153,434,255.
Example:
1 x 153,434,255 = 153,434,255
and
-1 x -153,434,255 = 153,434,255
Notice both answers equal 153,434,255
With that explanation out of the way, let's continue. Next, we take the number 153,434,255 and divide it by 2:
153,434,255 ÷ 2 = 76,717,127.5
If the quotient is a whole number, then 2 and 76,717,127.5 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 | 153,434,255 | |
| -1 | -153,434,255 |
Now, we try dividing 153,434,255 by 3:
153,434,255 ÷ 3 = 51,144,751.6667
If the quotient is a whole number, then 3 and 51,144,751.6667 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 | 153,434,255 | |
| -1 | -153,434,255 |
Let's try dividing by 4:
153,434,255 ÷ 4 = 38,358,563.75
If the quotient is a whole number, then 4 and 38,358,563.75 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 | 153,434,255 | |
| -1 | 153,434,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 107 | 169 | 535 | 845 | 1,391 | 1,697 | 6,955 | 8,485 | 18,083 | 22,061 | 90,415 | 110,305 | 181,579 | 286,793 | 907,895 | 1,433,965 | 2,360,527 | 11,802,635 | 30,686,851 | 153,434,255 |
| -1 | -5 | -13 | -65 | -107 | -169 | -535 | -845 | -1,391 | -1,697 | -6,955 | -8,485 | -18,083 | -22,061 | -90,415 | -110,305 | -181,579 | -286,793 | -907,895 | -1,433,965 | -2,360,527 | -11,802,635 | -30,686,851 | -153,434,255 |
