There are 5: 11,13,17,19,23
the prime numbers between 8 and 24 are 11, 13, 17, 19 and 23 so five
24 is a composite number.24 is NOT a prime number.
There are eight prime numbers under 20.
8 numbers.
There are 8.There are 8.There are 8.There are 8.
The prime numbers less than 100 that contain an 8 are 83 and 89. So, there are two prime numbers that are less than 100 and contain an 8.
To work this out, you need to write the numbers as the product of their prime factors: 24 = 2x2x2x3 64 = 2x2x2x2x2x2 The next step is to identify any common prime factors. In this case both numbers have three 2s as prime factors. Multiply these together and you get: 2x2x2 = 8 Thus the HCF of 24 and 64 is 8.
24 is composite because it can factored or split up as 24 = 3 * 8 for example. Prime numbers, such as 23, can not be split into factors.
8 of them.
Two numbers: 5 and 7 :)
17 is a prime number. 8 and 12 are not prime numbers.
