They are: 5*7*11 = 385

As a product of its prime factors: 3*3*3*5 = 135

As a product of its prime factors: 3*7*7 = 147

2 and 3 are the only consecutive primes.

3 x 7 x 37 = 777

As a product of its prime factors: 3*5 = 15 or 3+5+7 = 15

As a product of its prime factors: 3*3*5*5 = 225

3 and 7.

twin primes are 2 prime numbers with a difference of 2 the prime numbers 5 and 3 are twin primes because 5 minus 3 equals 2 so 109 and 111 are not twin primes

As a product of its prime factors: 2*2*3*3*7 = 252

2 and 3.

3 × 7 × 11

yes you can multiply 3 by 77 will give you 385 happy now?

Because the definition of twin primes is: two prime numbers with a difference of 2. 3 and 5 are both prime numbers, and their difference is 5 - 3 = 2 → they are twin primes.

It is: 3*3*3 = 27

It is: 2*3*3 = 18

385/100 = 77/20, or 3 17/20

Not true. 2 + 3 = 5, where all three are primes. One of the primes in the sum must be 2, otherwise both primes would be odd and their sum would be even (and >2) and therefore not prime. Such primes: p and p+2 [3 and 5 in the above example] are known as twin primes and there are infiitely many twin primes.

2, 3 and 5

3

Yes, they are.

Well, to begin with, 2 and 3 are not twin primes. The first twin primes are 3 and 5, but then 5 and 7 are also twin primes. After that, it's 11 and 13, then 17 and 19, 29 and 31, and 41 and 43. Twin primes are distinguished by having a difference of 2 between them.

21 factors into the primes 3 and 7; 24 factors into the primes 3 and 23. Therefore, the highest common integral factor is 3.
