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 222,532,531, 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 | 222,532,531 | |
| -1 | -222,532,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 222,532,531.
Example:
1 x 222,532,531 = 222,532,531
and
-1 x -222,532,531 = 222,532,531
Notice both answers equal 222,532,531
With that explanation out of the way, let's continue. Next, we take the number 222,532,531 and divide it by 2:
222,532,531 ÷ 2 = 111,266,265.5
If the quotient is a whole number, then 2 and 111,266,265.5 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 | 222,532,531 | |
| -1 | -222,532,531 |
Now, we try dividing 222,532,531 by 3:
222,532,531 ÷ 3 = 74,177,510.3333
If the quotient is a whole number, then 3 and 74,177,510.3333 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 | 222,532,531 | |
| -1 | -222,532,531 |
Let's try dividing by 4:
222,532,531 ÷ 4 = 55,633,132.75
If the quotient is a whole number, then 4 and 55,633,132.75 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 | 222,532,531 | |
| -1 | 222,532,531 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 71 | 689 | 923 | 3,763 | 4,549 | 48,919 | 59,137 | 241,097 | 322,979 | 3,134,261 | 4,198,727 | 17,117,887 | 222,532,531 |
| -1 | -13 | -53 | -71 | -689 | -923 | -3,763 | -4,549 | -48,919 | -59,137 | -241,097 | -322,979 | -3,134,261 | -4,198,727 | -17,117,887 | -222,532,531 |
