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 21,443,429, 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 | 21,443,429 | |
| -1 | -21,443,429 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 21,443,429.
Example:
1 x 21,443,429 = 21,443,429
and
-1 x -21,443,429 = 21,443,429
Notice both answers equal 21,443,429
With that explanation out of the way, let's continue. Next, we take the number 21,443,429 and divide it by 2:
21,443,429 ÷ 2 = 10,721,714.5
If the quotient is a whole number, then 2 and 10,721,714.5 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 | 21,443,429 | |
| -1 | -21,443,429 |
Now, we try dividing 21,443,429 by 3:
21,443,429 ÷ 3 = 7,147,809.6667
If the quotient is a whole number, then 3 and 7,147,809.6667 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 | 21,443,429 | |
| -1 | -21,443,429 |
Let's try dividing by 4:
21,443,429 ÷ 4 = 5,360,857.25
If the quotient is a whole number, then 4 and 5,360,857.25 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 | 21,443,429 | |
| -1 | 21,443,429 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 49 | 53 | 161 | 359 | 371 | 1,127 | 1,219 | 2,513 | 2,597 | 8,257 | 8,533 | 17,591 | 19,027 | 57,799 | 59,731 | 133,189 | 404,593 | 437,621 | 932,323 | 3,063,347 | 21,443,429 |
| -1 | -7 | -23 | -49 | -53 | -161 | -359 | -371 | -1,127 | -1,219 | -2,513 | -2,597 | -8,257 | -8,533 | -17,591 | -19,027 | -57,799 | -59,731 | -133,189 | -404,593 | -437,621 | -932,323 | -3,063,347 | -21,443,429 |
