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 224,474,185, 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 | 224,474,185 | |
| -1 | -224,474,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 224,474,185.
Example:
1 x 224,474,185 = 224,474,185
and
-1 x -224,474,185 = 224,474,185
Notice both answers equal 224,474,185
With that explanation out of the way, let's continue. Next, we take the number 224,474,185 and divide it by 2:
224,474,185 ÷ 2 = 112,237,092.5
If the quotient is a whole number, then 2 and 112,237,092.5 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 | 224,474,185 | |
| -1 | -224,474,185 |
Now, we try dividing 224,474,185 by 3:
224,474,185 ÷ 3 = 74,824,728.3333
If the quotient is a whole number, then 3 and 74,824,728.3333 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 | 224,474,185 | |
| -1 | -224,474,185 |
Let's try dividing by 4:
224,474,185 ÷ 4 = 56,118,546.25
If the quotient is a whole number, then 4 and 56,118,546.25 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 | 224,474,185 | |
| -1 | 224,474,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 283 | 1,415 | 3,679 | 12,203 | 18,395 | 61,015 | 158,639 | 793,195 | 3,453,449 | 17,267,245 | 44,894,837 | 224,474,185 |
| -1 | -5 | -13 | -65 | -283 | -1,415 | -3,679 | -12,203 | -18,395 | -61,015 | -158,639 | -793,195 | -3,453,449 | -17,267,245 | -44,894,837 | -224,474,185 |
