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 545,341,153, 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 | 545,341,153 | |
| -1 | -545,341,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 545,341,153.
Example:
1 x 545,341,153 = 545,341,153
and
-1 x -545,341,153 = 545,341,153
Notice both answers equal 545,341,153
With that explanation out of the way, let's continue. Next, we take the number 545,341,153 and divide it by 2:
545,341,153 ÷ 2 = 272,670,576.5
If the quotient is a whole number, then 2 and 272,670,576.5 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 | 545,341,153 | |
| -1 | -545,341,153 |
Now, we try dividing 545,341,153 by 3:
545,341,153 ÷ 3 = 181,780,384.3333
If the quotient is a whole number, then 3 and 181,780,384.3333 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 | 545,341,153 | |
| -1 | -545,341,153 |
Let's try dividing by 4:
545,341,153 ÷ 4 = 136,335,288.25
If the quotient is a whole number, then 4 and 136,335,288.25 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 | 545,341,153 | |
| -1 | 545,341,153 |
If you did it right, you will end up with this table:
| 1 | 7 | 173 | 401 | 1,123 | 1,211 | 2,807 | 7,861 | 69,373 | 194,279 | 450,323 | 485,611 | 1,359,953 | 3,152,261 | 77,905,879 | 545,341,153 |
| -1 | -7 | -173 | -401 | -1,123 | -1,211 | -2,807 | -7,861 | -69,373 | -194,279 | -450,323 | -485,611 | -1,359,953 | -3,152,261 | -77,905,879 | -545,341,153 |
