They're all positive integers under 30.
The first five prime numbers above 10 are: 11, 13, 17, 19, 23.
The first ten prime numbers are 2,3,5,7,11,13,17,19,23 and 29.
There is no relatively prime number for 10. Relatively Prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.

2,3,5,7,11,13,17,19,23,29- that's the first 10
An HCF is the product of any common prime factors of two numbers. If two numbers have no common prime factors, then the HCF will be 1. For example, 10 and 21. The prime factors are 2x5 and 3x7. There is nothing in common, and so the HCF of 10 and 21 is 1. Two consecutive numbers will always have the HCF of 1.
The first prime numbers 10 are: 1, 2, 3, 5, 7, 11, 13, 17, 19 and 23.
If the least common multiple of two numbers equals the product of the two numbers, then the numbers are relatively prime, that is their highest common factor is 1. For example, the numbers 10 and 21: The lcm is 10 x 21 = 210 They are relatively prime since their hcf is 1.
To find the least common multiples of two numbers, you have to first split them into their prime factors: 15 = 3x5 10 = 2x5 The next step is to identify any common prime factors. In this case both numbers have a 5 as a prime factor, so one of these can be discarded. Take every other prime factor (2, 3 and 5) and multiply them together: 2x3x5 = 30 Thus the least common multiple of 15 and 10 is 30.
There are more than 10 prime numbers
10 does not have 6 prime numbers.
The first step to working out the GCF of two numbers is to break them down into their prime factors. In this case it would be: 36x = 2*2*3*3*x 10 = 2*5 The next step is identifying any common prime factors. Both numbers have a 2 as a prime factor. It is unknown if x has a prime factor of 5. If it does not, then the GCF of 36x and 10 would be 2. If it does, then the GCF of 36x and 10 would be 10.
