Question

If two numbers are co- primes, atleast one of them must be prime.

Answer 1

Answer:

Step-by-step explanation:

True. This is because if a number is divisible by two given co-prime numbers then it is also divisible by their product. We know that 9 and 10 are co-primes and their product is equal to 90. (e) If two numbers are co-primes, at least one of them must be prime.

Answer 2

Answer:

If two numbers are co-prime that is not necessary that one of them must be a prime number. For example 8 and 9 are co-prime numbers but none of them are prime numbers.
