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 276,620,575, 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 | 276,620,575 | |
| -1 | -276,620,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 276,620,575.
Example:
1 x 276,620,575 = 276,620,575
and
-1 x -276,620,575 = 276,620,575
Notice both answers equal 276,620,575
With that explanation out of the way, let's continue. Next, we take the number 276,620,575 and divide it by 2:
276,620,575 ÷ 2 = 138,310,287.5
If the quotient is a whole number, then 2 and 138,310,287.5 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 | 276,620,575 | |
| -1 | -276,620,575 |
Now, we try dividing 276,620,575 by 3:
276,620,575 ÷ 3 = 92,206,858.3333
If the quotient is a whole number, then 3 and 92,206,858.3333 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 | 276,620,575 | |
| -1 | -276,620,575 |
Let's try dividing by 4:
276,620,575 ÷ 4 = 69,155,143.75
If the quotient is a whole number, then 4 and 69,155,143.75 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 | 276,620,575 | |
| -1 | 276,620,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 1,925 | 143,699 | 718,495 | 1,005,893 | 1,580,689 | 3,592,475 | 5,029,465 | 7,903,445 | 11,064,823 | 25,147,325 | 39,517,225 | 55,324,115 | 276,620,575 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -1,925 | -143,699 | -718,495 | -1,005,893 | -1,580,689 | -3,592,475 | -5,029,465 | -7,903,445 | -11,064,823 | -25,147,325 | -39,517,225 | -55,324,115 | -276,620,575 |
