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 224,154,421, 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 | 224,154,421 | |
| -1 | -224,154,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 224,154,421.
Example:
1 x 224,154,421 = 224,154,421
and
-1 x -224,154,421 = 224,154,421
Notice both answers equal 224,154,421
With that explanation out of the way, let's continue. Next, we take the number 224,154,421 and divide it by 2:
224,154,421 ÷ 2 = 112,077,210.5
If the quotient is a whole number, then 2 and 112,077,210.5 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 | 224,154,421 | |
| -1 | -224,154,421 |
Now, we try dividing 224,154,421 by 3:
224,154,421 ÷ 3 = 74,718,140.3333
If the quotient is a whole number, then 3 and 74,718,140.3333 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 | 224,154,421 | |
| -1 | -224,154,421 |
Let's try dividing by 4:
224,154,421 ÷ 4 = 56,038,605.25
If the quotient is a whole number, then 4 and 56,038,605.25 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 | 224,154,421 | |
| -1 | 224,154,421 |
If you did it right, you will end up with this table:
| 1 | 41 | 47 | 89 | 1,307 | 1,927 | 3,649 | 4,183 | 53,587 | 61,429 | 116,323 | 171,503 | 2,518,589 | 4,769,243 | 5,467,181 | 224,154,421 |
| -1 | -41 | -47 | -89 | -1,307 | -1,927 | -3,649 | -4,183 | -53,587 | -61,429 | -116,323 | -171,503 | -2,518,589 | -4,769,243 | -5,467,181 | -224,154,421 |
