The largest single digit composite number is 9. The largest prime number is 17 million digits long. The definition of a composite number is any number that has at least one positive divisor other than one or the number itself (it is not a prime number). The largest composite digit is therefore longer than the largest prime number by at leaf +1.

679 is the product of the largest single-digit prime number and the largest two-digit prime number.

There are five digits. A digit is each single number in the number as a whole: 6-7-3-9-2

81 is.

A single digit in a number can have a place value. A number with several digits cannot.

Yes you can enter a number as text in which case you can enter I believe up to 256 digits. or you can enter 15 single digits numbers into 15 different cells or you can enter a single 15 digit number in a single cell (this is the physical limit set by the software on how many digits a number can be allowed to have) though it will most likely be displayed in scientific notation unless you format it differently.

To be an even number then the final digit = 2. The largest single prime digit is 7 (as both 8 and 9 are composite). The greatest even number fulfilling the conditions is 77777772.
