5
Negative numbers don't have prime factorizations.
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.
72
Negative numbers don't have prime factorizations.
5 c
there is no prime factorization of 72 except for 1 and 72
49 = 7 x 7 or 72
2
72 = 2*2*2*3*3 108 = 2*2*3*3*3
12 x 6 = 72, so their prime factorizations are the same. Prime Factorization of : 12 x 6 and 72 = (2 * 2 * 3) (2 * 3) = 2 * 2 * 2 * 3 * 3
The prime factorization of 72 is: 2 x 2 x 2 x 3 x 3
Some prime factorizations have repeated factors. The prime factorization of 72 is 2 x 2 x 2 x 3 x 3. The distinct prime factors of 72 are 2 and 3.
