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 76,275,475, 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 | 76,275,475 | |
| -1 | -76,275,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,275,475.
Example:
1 x 76,275,475 = 76,275,475
and
-1 x -76,275,475 = 76,275,475
Notice both answers equal 76,275,475
With that explanation out of the way, let's continue. Next, we take the number 76,275,475 and divide it by 2:
76,275,475 ÷ 2 = 38,137,737.5
If the quotient is a whole number, then 2 and 38,137,737.5 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 | 76,275,475 | |
| -1 | -76,275,475 |
Now, we try dividing 76,275,475 by 3:
76,275,475 ÷ 3 = 25,425,158.3333
If the quotient is a whole number, then 3 and 25,425,158.3333 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 | 76,275,475 | |
| -1 | -76,275,475 |
Let's try dividing by 4:
76,275,475 ÷ 4 = 19,068,868.75
If the quotient is a whole number, then 4 and 19,068,868.75 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 | 76,275,475 | |
| -1 | 76,275,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 109 | 115 | 545 | 575 | 1,217 | 2,507 | 2,725 | 6,085 | 12,535 | 27,991 | 30,425 | 62,675 | 132,653 | 139,955 | 663,265 | 699,775 | 3,051,019 | 3,316,325 | 15,255,095 | 76,275,475 |
| -1 | -5 | -23 | -25 | -109 | -115 | -545 | -575 | -1,217 | -2,507 | -2,725 | -6,085 | -12,535 | -27,991 | -30,425 | -62,675 | -132,653 | -139,955 | -663,265 | -699,775 | -3,051,019 | -3,316,325 | -15,255,095 | -76,275,475 |
