Factor pairs equal a given number, when multiplied together in factorization. Every number has at least one factor pair: 1 and itself. Numbers that can only be factored by 1 and themselves are prime numbers. Because 54 has more than one factorization, it is a composite number.

Multiplying 1 and 54 produces 54, as does 3 and 18, 2 and 27, and 6 and 9. Each of these is a factor pair of 54.

Prime factorization produces a number, using only the prime number factors. The prime numbers of 54 are 2 and 3, because each of these numbers has exactly one factor pair. Therefore, the prime factorization of 54 is 2 multiplied by 3 multiplied by 3 multiplied by 3.

In a multiplication table, the numbers in the first row and the first column are all factors, and the numbers in the interior rows and columns are all products. To use the table to find the answer to a multiplication problem, locate one factor in the first row and the other factor in the first column. The number in the interior square where the column and row meet is the product of the problem.
