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 222,154,645, 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 | 222,154,645 | |
| -1 | -222,154,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,154,645.
Example:
1 x 222,154,645 = 222,154,645
and
-1 x -222,154,645 = 222,154,645
Notice both answers equal 222,154,645
With that explanation out of the way, let's continue. Next, we take the number 222,154,645 and divide it by 2:
222,154,645 ÷ 2 = 111,077,322.5
If the quotient is a whole number, then 2 and 111,077,322.5 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 | 222,154,645 | |
| -1 | -222,154,645 |
Now, we try dividing 222,154,645 by 3:
222,154,645 ÷ 3 = 74,051,548.3333
If the quotient is a whole number, then 3 and 74,051,548.3333 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 | 222,154,645 | |
| -1 | -222,154,645 |
Let's try dividing by 4:
222,154,645 ÷ 4 = 55,538,661.25
If the quotient is a whole number, then 4 and 55,538,661.25 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 | 222,154,645 | |
| -1 | 222,154,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 199 | 995 | 5,771 | 7,699 | 28,855 | 38,495 | 223,271 | 1,116,355 | 1,532,101 | 7,660,505 | 44,430,929 | 222,154,645 |
| -1 | -5 | -29 | -145 | -199 | -995 | -5,771 | -7,699 | -28,855 | -38,495 | -223,271 | -1,116,355 | -1,532,101 | -7,660,505 | -44,430,929 | -222,154,645 |
