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 194,467,225, 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 | 194,467,225 | |
| -1 | -194,467,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 194,467,225.
Example:
1 x 194,467,225 = 194,467,225
and
-1 x -194,467,225 = 194,467,225
Notice both answers equal 194,467,225
With that explanation out of the way, let's continue. Next, we take the number 194,467,225 and divide it by 2:
194,467,225 ÷ 2 = 97,233,612.5
If the quotient is a whole number, then 2 and 97,233,612.5 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 | 194,467,225 | |
| -1 | -194,467,225 |
Now, we try dividing 194,467,225 by 3:
194,467,225 ÷ 3 = 64,822,408.3333
If the quotient is a whole number, then 3 and 64,822,408.3333 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 | 194,467,225 | |
| -1 | -194,467,225 |
Let's try dividing by 4:
194,467,225 ÷ 4 = 48,616,806.25
If the quotient is a whole number, then 4 and 48,616,806.25 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 | 194,467,225 | |
| -1 | 194,467,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 71 | 89 | 355 | 445 | 1,231 | 1,775 | 2,225 | 6,155 | 6,319 | 30,775 | 31,595 | 87,401 | 109,559 | 157,975 | 437,005 | 547,795 | 2,185,025 | 2,738,975 | 7,778,689 | 38,893,445 | 194,467,225 |
| -1 | -5 | -25 | -71 | -89 | -355 | -445 | -1,231 | -1,775 | -2,225 | -6,155 | -6,319 | -30,775 | -31,595 | -87,401 | -109,559 | -157,975 | -437,005 | -547,795 | -2,185,025 | -2,738,975 | -7,778,689 | -38,893,445 | -194,467,225 |
