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 102,623,677, 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 | 102,623,677 | |
| -1 | -102,623,677 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 102,623,677.
Example:
1 x 102,623,677 = 102,623,677
and
-1 x -102,623,677 = 102,623,677
Notice both answers equal 102,623,677
With that explanation out of the way, let's continue. Next, we take the number 102,623,677 and divide it by 2:
102,623,677 ÷ 2 = 51,311,838.5
If the quotient is a whole number, then 2 and 51,311,838.5 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 | 102,623,677 | |
| -1 | -102,623,677 |
Now, we try dividing 102,623,677 by 3:
102,623,677 ÷ 3 = 34,207,892.3333
If the quotient is a whole number, then 3 and 34,207,892.3333 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 | 102,623,677 | |
| -1 | -102,623,677 |
Let's try dividing by 4:
102,623,677 ÷ 4 = 25,655,919.25
If the quotient is a whole number, then 4 and 25,655,919.25 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 | 102,623,677 | |
| -1 | 102,623,677 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 151 | 299 | 1,963 | 2,273 | 3,473 | 29,549 | 45,149 | 52,279 | 343,223 | 679,627 | 4,461,899 | 7,894,129 | 102,623,677 |
| -1 | -13 | -23 | -151 | -299 | -1,963 | -2,273 | -3,473 | -29,549 | -45,149 | -52,279 | -343,223 | -679,627 | -4,461,899 | -7,894,129 | -102,623,677 |
