What are the factors of a composite number?
Prime numbers have only two factors, the number 1 1 and the prime number itself. Composite numbers have more than two factors, and every composite number can be written as a unique product of primes. This is called the prime factorization of a number.
Which is the positive pair factor of 28?
1 × 28 = 28, then (1, 28) is a pair factor of 28. 28 × 1 = 28, then (28, 1) is a pair factor of 28. Here, the pair factor (1, 28) is the same as the pair factor (28, 1), (2, 14) is the same as the pair factor (14, 2), and (7, 4) is the same as the pair factor (4, 7) Therefore, the positive pair factors are (1, 28), (2, 14), and (7, 4).
