22 x 5
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
The prime numbers that go into 65 are 5 and 13. This is because 65 can be factored into 5 × 13, where both 5 and 13 are prime numbers. Therefore, the prime factorization of 65 is 5 and 13.
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.
The prime numbers that go into 65 are 5 and 13. This is because 65 can be factored into 5 × 13, where both 5 and 13 are prime numbers. Therefore, the prime factorization of 65 is 5 and 13.
These are the prime numbers 1-20 2,3,5,7,11,13,17,19
