28 = 2x2x7
composite
All composite numbers can be expressed as unique products of prime numbers. This is known as a prime factorization.
It is: 3*3*3 = 27
28 = 2 × 2 × 7 = 2² × 7.
45 factored into prime numbers is: 5 x 9 5 x 3 x 3
composite
28 = 2x2x7
composite
All composite numbers can be expressed as unique products of prime numbers. This is known as a prime factorization.
No. 9 can be factored into 3 and 3, and 33 can be factored into 3 and 11.
Because any number with any proper factors is by definition not prime.
It is: 3*3*3 = 27
2269 is a prime number so, it can't be further factored into prime numbers. Prime factorization of 2269 = 2269.
17/20 is the simplest form. While 20 is a composite number, 17 is prime. Thus no numbers other than 17 (and 1) could be factored out and 17 does not go into 20.
These are the prime numbers 1-20 2,3,5,7,11,13,17,19
28 = 2 × 2 × 7 = 2² × 7.
