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 8,986,549, 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 | 8,986,549 | |
| -1 | -8,986,549 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,986,549.
Example:
1 x 8,986,549 = 8,986,549
and
-1 x -8,986,549 = 8,986,549
Notice both answers equal 8,986,549
With that explanation out of the way, let's continue. Next, we take the number 8,986,549 and divide it by 2:
8,986,549 ÷ 2 = 4,493,274.5
If the quotient is a whole number, then 2 and 4,493,274.5 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 | 8,986,549 | |
| -1 | -8,986,549 |
Now, we try dividing 8,986,549 by 3:
8,986,549 ÷ 3 = 2,995,516.3333
If the quotient is a whole number, then 3 and 2,995,516.3333 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 | 8,986,549 | |
| -1 | -8,986,549 |
Let's try dividing by 4:
8,986,549 ÷ 4 = 2,246,637.25
If the quotient is a whole number, then 4 and 2,246,637.25 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 | 8,986,549 | |
| -1 | 8,986,549 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 29 | 121 | 143 | 197 | 319 | 377 | 1,573 | 2,167 | 2,561 | 3,509 | 4,147 | 5,713 | 23,837 | 28,171 | 45,617 | 62,843 | 74,269 | 309,881 | 691,273 | 816,959 | 8,986,549 |
| -1 | -11 | -13 | -29 | -121 | -143 | -197 | -319 | -377 | -1,573 | -2,167 | -2,561 | -3,509 | -4,147 | -5,713 | -23,837 | -28,171 | -45,617 | -62,843 | -74,269 | -309,881 | -691,273 | -816,959 | -8,986,549 |
