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 2,551,367, 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 | 2,551,367 | |
| -1 | -2,551,367 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,551,367.
Example:
1 x 2,551,367 = 2,551,367
and
-1 x -2,551,367 = 2,551,367
Notice both answers equal 2,551,367
With that explanation out of the way, let's continue. Next, we take the number 2,551,367 and divide it by 2:
2,551,367 ÷ 2 = 1,275,683.5
If the quotient is a whole number, then 2 and 1,275,683.5 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 | 2,551,367 | |
| -1 | -2,551,367 |
Now, we try dividing 2,551,367 by 3:
2,551,367 ÷ 3 = 850,455.6667
If the quotient is a whole number, then 3 and 850,455.6667 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 | 2,551,367 | |
| -1 | -2,551,367 |
Let's try dividing by 4:
2,551,367 ÷ 4 = 637,841.75
If the quotient is a whole number, then 4 and 637,841.75 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 | 2,551,367 | |
| -1 | 2,551,367 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 23 | 53 | 91 | 161 | 299 | 371 | 529 | 689 | 1,219 | 2,093 | 3,703 | 4,823 | 6,877 | 8,533 | 15,847 | 28,037 | 48,139 | 110,929 | 196,259 | 364,481 | 2,551,367 |
| -1 | -7 | -13 | -23 | -53 | -91 | -161 | -299 | -371 | -529 | -689 | -1,219 | -2,093 | -3,703 | -4,823 | -6,877 | -8,533 | -15,847 | -28,037 | -48,139 | -110,929 | -196,259 | -364,481 | -2,551,367 |
