If there are no prime factors in common, the GCF is 1.

A, B and C aren't numbers, they're letters. Probably variables. Without knowing what numbers they represent, we can't calculate their LCM.
Rub them together and see which one gets scratched.
If the prime factorization contains a 5 and a 7, 35 is a factor.
101, 173 and 911 are all prime numbers. 173911 is not.
If the prime factorizations have no prime factors in common, the numbers are relatively prime.
If the prime factorizations have no factors in common, the LCM is the product of them.
If the prime factorizations contain no factors in common (their GCF is 1), the numbers are relatively prime.
Use the prime factorizations to determine the GCF. If the GCF is 1, the numbers are relatively prime. If the two numbers have no prime factors in common, they are relatively prime.
If none of the prime factors are in common, the LCM will be the product of the two.
You CAN'T determine whether two numbers are proportional, just by looking at one number from each set.
imaginary
If they have no common factors other than 1.

Observe the patient, and determine whether you are looking at the person's left thigh or right thigh.
Example: 30 and 42Factor them.2 x 3 x 5 = 302 x 3 x 7 = 42Combine the factors, eliminating duplicates.2 x 3 x 5 x 7 = 210, the LCMIf there are no common prime factors, the LCM is the product of the original two numbers.
If it has more than two factors.
