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 42,076,895, 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 | 42,076,895 | |
| -1 | -42,076,895 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 42,076,895.
Example:
1 x 42,076,895 = 42,076,895
and
-1 x -42,076,895 = 42,076,895
Notice both answers equal 42,076,895
With that explanation out of the way, let's continue. Next, we take the number 42,076,895 and divide it by 2:
42,076,895 ÷ 2 = 21,038,447.5
If the quotient is a whole number, then 2 and 21,038,447.5 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 | 42,076,895 | |
| -1 | -42,076,895 |
Now, we try dividing 42,076,895 by 3:
42,076,895 ÷ 3 = 14,025,631.6667
If the quotient is a whole number, then 3 and 14,025,631.6667 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 | 42,076,895 | |
| -1 | -42,076,895 |
Let's try dividing by 4:
42,076,895 ÷ 4 = 10,519,223.75
If the quotient is a whole number, then 4 and 10,519,223.75 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 | 42,076,895 | |
| -1 | 42,076,895 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 193 | 965 | 1,351 | 6,229 | 6,755 | 31,145 | 43,603 | 218,015 | 1,202,197 | 6,010,985 | 8,415,379 | 42,076,895 |
| -1 | -5 | -7 | -35 | -193 | -965 | -1,351 | -6,229 | -6,755 | -31,145 | -43,603 | -218,015 | -1,202,197 | -6,010,985 | -8,415,379 | -42,076,895 |
