Explain why, when a number is composite, its least whole number divisor, other than 1, must be prime. Question content area bottom Part 1 Choose the correct answer below. A. A composite number is a number that is the result of a product of primes. Every divisor of a composite number is prime, so the least whole number divisor must also be prime. B. A composite number can be written as a product of other numbers, because 2 and 3 are the least positive whole numbers other than 1, and are both prime, the least whole number divisor of a composite number must be prime. C. If a number d divides a number n, then every number which divides d also divides n. If the least whole number divisor other than 1 was not prime, then it would have a factor other than one and itself and this factor would also divide n. D. A composite number has no factors other than 1 and itself, so the least whole number divisor other than 1 would be the number itself, which is prime
