There are 15 prime numbers up to 50.
22
The prime numbers between 15 and 30 are: 17 19 23 29.
Numbers are either prime or they aren't. In this case, 45 is divisible by 3 and 15; sixty-four goes into 2, 4, 8 and 32. The term "relatively prime" compares two numbers and their common factors. If the GCF of the two numbers is 1, then they are "relatively prime."
2 + 13
15 is the product of two prime numbers; 3 x 5
2 and 13
No. 15 is the product of two prime numbers: 3 and 5
They are: 2+13 = 15

13 and 2
20
The prime numbers between 15 and 20 are 17 and 19. To find the product of these two prime numbers, you simply multiply them together: 17 x 19 = 323. Therefore, the product of the prime numbers between 15 and 20 is 323.
No, they are composite numbers. The factors of 15 are 1, 3, 5, and 15. The factors of 33 are 1, 3, 11, and 33. Prime numbers have two factors: 1 and the number itself, so 15 and 33 cannot be prime.
