As a product of its prime numbers: 3*7*11 = 231

11+13+19=43 all are prime numbers and these are the only three that are above 7 and work.

The factors of 12 are: 1,2,3,4,6. The prime factors are the prime numbers in the factors. So: 1,2,3 are the prime factors of 12.

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.

45 Divide by three. 15,3 Divide by three. 5,3,3 Stop.

state if the three numbers can be measures of the sides of a triangle. show your work 1- 15,12,9

Firstly, you should recognize the relevant numbers which are 23 and 29. Now let us work out. Every even number is divisible by two, hence not prime. So we can exclude 22, 24, 26 and 28. Meanwhile 21, (24) and 27 are divisible by three. 25 is divisible by 5. The remaining numbers 23 and 29 have no divisors other than 1 and the number itself, hence they are the prime numbers.

2 x 2 x 3 x 7 = 84
