To distinguish them from prime numbers. Composite means "made up of various parts or elements." Prime numbers have one and only one factor pair. Composite numbers have a various number of factor pairs, but always more than one.
This would be called a "factor". A number may be made by multiplying two or more other numbers together. The numbers that are multiplied together are called factors of the final number.
Integers greater than 1, that are not prime numbers, are called composite numbers, because they are "made up of" more than one prime factor.
They are mold numbers. Only a certain number of molds were made for each piece, and the numbers tell which mold each piece came out of.
Backstamps are marks that appear on the underside of a ceramic to identify the manufacturer. ... You may not see a "Made in Germany" mark, but the piece could have been manufactured there. cutt.ly/xhVPf6M

Every natural number has factors. A factor is any number that will evenly (or wholly) divide the first number leaving no "remainder". So 5 is a factor of 10, because 10 divided by 5 is exactly 2 with nothing left over. A "common factor" is any factor that two or more numbers share in common. So 8 and 12 have a common factor of 4, that is, they both have 4 as a factor. The numbers, 24, 18, 15, and 21 possess a common factor of 3. The "greatest common factor" is the largest such factor that two numbers share in common. For example: given the two numbers 12 and 6, which have common factors of 1, 2, 3, 4 and 6, the greatest (or 'highest') common factor is 6. NOTE: A single number in itself cannot have a "common" factor, even though, as stated, it has factors of itself. The term "common" means that more than one number must be involved so that a comparison of factors can be made between the numbers to see what factor is common to all/both.
