Steps to Determine if 48 is Prime or Composite

To classify 48 as prime or composite, follow these systematic steps:

1. Understand the Definitions:

   • A prime number is a natural number greater than 1 that has no divisors other than 1 and itself. Examples include 2, 3, 5, and 7.
   • A composite number is a natural number greater than 1 that has more than two divisors. Examples include 4, 6, 8, and 9.

2. Check for Even Divisibility:
   Since 48 is an even number, it is divisible by 2. This immediately disqualifies it from being prime, as primes cannot have divisors other than 1 and themselves.

3. List All Factors:
   Find all integers that divide 48 without leaving a remainder. The factors of 48 are:

   • 1, 2, 3, 4, 6, 8, 12, 16, 24, 48.
     With 10 total factors, 48 clearly fits the composite category.

4. Apply the Sieve Method:
   Test divisibility by primes up to the square root of 48 (approximately 6.9). Check 2, 3, and 5:

   • 48 ÷ 2 = 24 (divisible)
   • 48 ÷ 3 = 16 (divisible)
   • 48 ÷ 5 = 9.6 (not divisible).
     Since 48 is divisible by 2 and 3, it is composite.
