No, 30 is not prime.
No on both counts. 4 is not prime and 4 is not a factor of 30.
No. The number 30 is composite and so it cannot be a prime factor.
The largest prime factor of 30 is 5 and its other prime factors are 2 and 3
8 is not a prime factor of 30. The prime factorization of 30 is 2x3x5.
Oh, dude, the whole number with the greatest prime factor between 1 and 30 is 30 itself. The greatest prime factor of 30 is 5, which is the largest prime number between 1 and 30. So, yeah, 30 takes the crown for this one.
30 15,2 5,3,2
5 The prime factors of 30 are 2, 3, 5
As a product of its prime factors: 2*3*5 = 30
30 has three prime numbers and is a factor of 60.
13 is a prime factor of itself Prime factors of 30 are: 2, 3 and 5
No, 30 and 40 are not relatively prime. Their greatest common factor is 10.
A factor of a composite number need not be a prime number, some factors are themselves composite. Prime factorisation is continuing to factorise each factor unless it is a prime. For example, start with 30. 6 goes into 30 so finding a factor is satisfied by simply identifying 6 as a factor of 30. Now 30 = 5*6 where 5 is a prime, but 6 is not so we need to factorise 6. 6 = 2*3 and therefore, 30 = 5*2*3 = 2*3*5 The last is the prime factorisation of 30.
