prime number is a number that could only be divided by itself and one. odd numbers are naturally not divisible by 2 but odd numbers can be divisible by other numbers. one example is 15. 15 is divisible by itself and one but also by 3 and 5.

No. 15 divided by 5 = 3

15

No, there are many odd numbers that are not prime: 9, 15, 21, 25, 27, etc. However, 2 is the only even number that is prime, since all other even numbers are divisible by 2.

You can elimate the even numbers 72 and 42 right away because the only even prime number is 2. Using the divisibility rules, you can eliminate 87; 8 + 7 = 15, which is divisible by 3, which means 87 is divisible by 3. 59 is the prime number.

because 9 and 15 aren't prime numbers they can be divisible by 3 and 5 it has to be prime numbers only

If you are asking for the prime numbers between 15 and 30, they are 17, 19, 23, and 29. This is because prime numbers are only divisible by themselves and 1.

15 is the product of two prime numbers; 3 x 5

3, 7 and 47 are prime numbers. 30 is not a prime since it is divisible by 2, 3, 5, 6, 10 and 15.

Composite numbers are numbers which are divisible by another number other than 1 and the number itself. Ex 1: 15 is divisible by 1, 3, 5 and 15. So, 15 is a composite number. Ex 2: 3 is divisible by 1 and 3 only. So, such numbers which are only divisible by 1 and the number itself are known as Prime numbers.

No. 15 is the product of two prime numbers: 3 and 5

Prime numbers are those which are divisible only by 1 and the number itself... Example: 7 is divisible by no number other than 7 and 1. Relatively prime numbers are those pairs of numbers which have no common divisor other than one. Example: (15,16) Factors of 15:1,3,5,15 Factors of 16:1,4,16 Common factor of 15 & 16 is 1, hence 15 & 16 are relatively prime.

Since both 3 and 5 are prime numbers, only numbers that are multiples of its product are the numbers that are divisible by both. 15 is the LCM of 3 and 5 and hence all multiples of 15 are divisible by both 3 and 5

15 is not a prime number because it is not only divisible by 1 and itself it is also divisible by 3.

The factors of 1,155 are: 1, 3, 5, 7, 11, 15, 33, 35, 77, 105, 165, 231, 385, and 1,155. 3, 5, 7, and 11 are prime numbers.
