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 26,620,363, 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 | 26,620,363 | |
| -1 | -26,620,363 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,620,363.
Example:
1 x 26,620,363 = 26,620,363
and
-1 x -26,620,363 = 26,620,363
Notice both answers equal 26,620,363
With that explanation out of the way, let's continue. Next, we take the number 26,620,363 and divide it by 2:
26,620,363 ÷ 2 = 13,310,181.5
If the quotient is a whole number, then 2 and 13,310,181.5 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 | 26,620,363 | |
| -1 | -26,620,363 |
Now, we try dividing 26,620,363 by 3:
26,620,363 ÷ 3 = 8,873,454.3333
If the quotient is a whole number, then 3 and 8,873,454.3333 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 | 26,620,363 | |
| -1 | -26,620,363 |
Let's try dividing by 4:
26,620,363 ÷ 4 = 6,655,090.75
If the quotient is a whole number, then 4 and 6,655,090.75 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 | 26,620,363 | |
| -1 | 26,620,363 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 53 | 77 | 121 | 371 | 583 | 593 | 847 | 4,081 | 4,151 | 6,413 | 6,523 | 31,429 | 44,891 | 45,661 | 71,753 | 220,003 | 345,719 | 502,271 | 2,420,033 | 3,802,909 | 26,620,363 |
| -1 | -7 | -11 | -53 | -77 | -121 | -371 | -583 | -593 | -847 | -4,081 | -4,151 | -6,413 | -6,523 | -31,429 | -44,891 | -45,661 | -71,753 | -220,003 | -345,719 | -502,271 | -2,420,033 | -3,802,909 | -26,620,363 |
