There are three numbers that fit those requirements.
61 and 73 are prime numbers. Prime numbers don't have prime factorizations, since their only prime factors are themselves. Since these would have to be different numbers, they don't have any prime factors in common. The GCF of any set of prime numbers is 1.
61 and 73 are both prime numbers. Prime numbers don't have prime factorizations since they only have one prime factor. The GCF of any set of different prime numbers is 1, since they don't have any prime factors in common.
Negative numbers don't have prime factorizations.
Factors go into numbers, numbers go into multiples.
Factors go into numbers, numbers go into multiples.Factors go into numbers, numbers go into multiples.
If the prime factorizations contain no factors in common (their GCF is 1), the numbers are relatively prime.
Prime factorizations are expressions of numbers as products of prime factors. The prime factorization of 30 is 2 x 3 x 5.
61 and 73 are prime numbers. Prime numbers don't have prime factorizations, since their only prime factors are themselves. Since these would have to be different numbers, they don't have any prime factors in common. The GCF of any set of prime numbers is 1.
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.
The prime factors of 42 are 2, 3 and 7.
61 and 73 are both prime numbers. Prime numbers don't have prime factorizations since they only have one prime factor. The GCF of any set of different prime numbers is 1, since they don't have any prime factors in common.
Prime factorizations are unique. No other number will have exactly the same number of prime factors as 28. Multiples of 14 will have some of the same factors.
If there are no prime factors in common, the GCF is 1.
If they have no prime factors in common, their GCF is 1.
If none of the prime factors are in common, the LCM will be the product of the two.
At least two.
