No. 10 is not a prime number, which means it cannot be a prime factor. It can be a factor, but not a prime factor.

120 = 2 * 2 * 2 * 3 * 5 Written as a product of powers is (2^3) * 3 * 5

No, 120 and 835 are not relatively prime.

120 is not a prime and no prime numbers equal a composite (ie non-prime).

No, 3 is a factor of both. Note that the digits of 120 add up to 3 and those of 147 add up to 12. Both are multiples of 3 so the numbers 120 s and 147 are divisible by 3 and not relatively prime

GCF of a prime number and a composite number is 1 if the prime number is not a factor of the composite number. Here 103 is a prime number and 120 is a composite number. And 120 is not divisible by 103(or 103 is not a factor of 120). So, GCF(103,120) = 1
