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 127,465,355, 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 | 127,465,355 | |
| -1 | -127,465,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 127,465,355.
Example:
1 x 127,465,355 = 127,465,355
and
-1 x -127,465,355 = 127,465,355
Notice both answers equal 127,465,355
With that explanation out of the way, let's continue. Next, we take the number 127,465,355 and divide it by 2:
127,465,355 ÷ 2 = 63,732,677.5
If the quotient is a whole number, then 2 and 63,732,677.5 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 | 127,465,355 | |
| -1 | -127,465,355 |
Now, we try dividing 127,465,355 by 3:
127,465,355 ÷ 3 = 42,488,451.6667
If the quotient is a whole number, then 3 and 42,488,451.6667 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 | 127,465,355 | |
| -1 | -127,465,355 |
Let's try dividing by 4:
127,465,355 ÷ 4 = 31,866,338.75
If the quotient is a whole number, then 4 and 31,866,338.75 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 | 127,465,355 | |
| -1 | 127,465,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 89 | 107 | 445 | 535 | 2,677 | 9,523 | 13,385 | 47,615 | 238,253 | 286,439 | 1,191,265 | 1,432,195 | 25,493,071 | 127,465,355 |
| -1 | -5 | -89 | -107 | -445 | -535 | -2,677 | -9,523 | -13,385 | -47,615 | -238,253 | -286,439 | -1,191,265 | -1,432,195 | -25,493,071 | -127,465,355 |
