all of these are except 4. 4 is not a prime number!
3*3*4
3 is a prime number. 4 and 10 are both composite numbers having 2 as a factor.
The prime numbers between 4 and 15 are 5, 7, 11, and 13. A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In this case, 5, 7, 11, and 13 meet this criteria and are thus prime numbers within the specified range.
a prime number has no factors other than one and itself 4:1,2,4 10:1,2,5,10 3:1,3 3 is the prime number!!!! it's only factors are one and itself!!!!
no, 12 can be made by 2 and 6, 3 and 4 and 15 can be made from 3 and 5, etc
No, 12 and 15 aren't relatively prime, because they both share as a prime factor 3. Dividing both12 and 15 by 3 gives 4 and 5 respectively. Consecutive numbers are always coprime. Coprime numbers are relatively prime to each other, as they share no prime factors, for example 33 and 35,
The prime numbers from 1 to 4 are 2 and 3.
No.
The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The prime numbers are 2, 3, and 5.
No, they are not.
5 and 11 are prime. The others are not (3 x 4 =12, 3 x 5 =15, 2 x 11 =22)
2 3 5 are prime numbers.
19 only has 2 factors - itself and 1. 15 has 4 factors - itself, 1, 3, and 5. Prime numbers can only have 2 factors. 19 is prime, 15 is composite.
3 x 5 = 15 15 x 4 = 60
1 1 2 1 2 3 1 2 3 4 1 4 3 2 5
The first four prime numbers after 3 are: 5, 7, 11, 13
