It is 3 because it has only two factors which are itself and one
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.
5 and 11 are prime. The others are not (3 x 4 =12, 3 x 5 =15, 2 x 11 =22)
No, they are not.
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
