The first number has prime factorisation 2 × 3 × 7 and the second number has prime factorisation 3 × 7 × 11 . Are they co-prime? Does one of them divide the other?

Given, Prime factorisation of the first number = 2 × 3 × 7 Prime factorisation of the second number = 3 × 7 × 11 We know that co-prime numbers are two or more numbers that have no common factors other than 1 . We can see that, 3 and 7 are the common factors of both the numbers. Hence, they are not co-primes. We can say that if one number is divisible by another, the prime factorisation of the second number is included in the prime factorisation of the first number. We can see that the prime factor 2 is not in the prime factorisation of the second number. Henve, the second number is not divisible by the first number.
