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 134,421,247, 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 | 134,421,247 | |
| -1 | -134,421,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,421,247.
Example:
1 x 134,421,247 = 134,421,247
and
-1 x -134,421,247 = 134,421,247
Notice both answers equal 134,421,247
With that explanation out of the way, let's continue. Next, we take the number 134,421,247 and divide it by 2:
134,421,247 ÷ 2 = 67,210,623.5
If the quotient is a whole number, then 2 and 67,210,623.5 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 | 134,421,247 | |
| -1 | -134,421,247 |
Now, we try dividing 134,421,247 by 3:
134,421,247 ÷ 3 = 44,807,082.3333
If the quotient is a whole number, then 3 and 44,807,082.3333 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 | 134,421,247 | |
| -1 | -134,421,247 |
Let's try dividing by 4:
134,421,247 ÷ 4 = 33,605,311.75
If the quotient is a whole number, then 4 and 33,605,311.75 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 | 134,421,247 | |
| -1 | 134,421,247 |
If you did it right, you will end up with this table:
| 1 | 41 | 61 | 71 | 757 | 2,501 | 2,911 | 4,331 | 31,037 | 46,177 | 53,747 | 177,571 | 1,893,257 | 2,203,627 | 3,278,567 | 134,421,247 |
| -1 | -41 | -61 | -71 | -757 | -2,501 | -2,911 | -4,331 | -31,037 | -46,177 | -53,747 | -177,571 | -1,893,257 | -2,203,627 | -3,278,567 | -134,421,247 |
