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 76,141,735, 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 | 76,141,735 | |
| -1 | -76,141,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 76,141,735.
Example:
1 x 76,141,735 = 76,141,735
and
-1 x -76,141,735 = 76,141,735
Notice both answers equal 76,141,735
With that explanation out of the way, let's continue. Next, we take the number 76,141,735 and divide it by 2:
76,141,735 ÷ 2 = 38,070,867.5
If the quotient is a whole number, then 2 and 38,070,867.5 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 | 76,141,735 | |
| -1 | -76,141,735 |
Now, we try dividing 76,141,735 by 3:
76,141,735 ÷ 3 = 25,380,578.3333
If the quotient is a whole number, then 3 and 25,380,578.3333 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 | 76,141,735 | |
| -1 | -76,141,735 |
Let's try dividing by 4:
76,141,735 ÷ 4 = 19,035,433.75
If the quotient is a whole number, then 4 and 19,035,433.75 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 | 76,141,735 | |
| -1 | 76,141,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 107 | 155 | 535 | 3,317 | 4,591 | 16,585 | 22,955 | 142,321 | 491,237 | 711,605 | 2,456,185 | 15,228,347 | 76,141,735 |
| -1 | -5 | -31 | -107 | -155 | -535 | -3,317 | -4,591 | -16,585 | -22,955 | -142,321 | -491,237 | -711,605 | -2,456,185 | -15,228,347 | -76,141,735 |
