Prime number chart | TPT - Free Printable

- The task is to identify the prime factorization for each number from 1 to 100 using the provided chart.
- Prime factorization breaks down a composite number into a product of prime numbers.
- For prime numbers (like 2, 3, 5, 7, etc.), the factorization is simply the number itself, as they have no other prime factors.
- For composite numbers, multiply the prime factors shown in the chart to verify they equal the original number (e.g., 4 = 2×2, 6 = 2×3, 8 = 2×2×2, 9 = 3×3, 10 = 2×5).
- The chart uses “PRIME” for prime numbers and lists the prime factors for composites, sometimes with exponents implied by repeated primes.
- To solve: Locate each number in the chart and write its prime factorization as shown. For example:
- 12 → 2×2×3
- 25 → 5×5
- 30 → 2×3×5
- 100 → 2×2×5×5
- This exercise reinforces understanding of primes, composites, and how all integers >1 can be uniquely expressed as products of primes.
