30
15,2
5,3,2
There are a few possibilities, but the correct ones will all end with some version of 2, 3 and 5.
30 15,2 5,3,2
Use a factor tree. 30 15,2 5,3,2
Use a factor tree. 30 15,2 5,3,2 2 x 3 x 5 = 30
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.
'13' is a prime number, so there is no factor tree. However, to test , we can say 13)13 = 1 When reduced to '1' the factoring is complete. Prime numbers are 2,3,5,7,11,13,17,19,23,29.... This goes to infinity, however, the above list is primes to '30'.
The largest prime factor of 30 is 5 and its other prime factors are 2 and 3
30 / \ 2 15 / / \ 1*2 5*3 2*5*3
The factor tree finds the prime factorization. The prime factorization finds the LCM. Example: 30 and 42 Factor them. 30 15,2 5,3,2 42 21,2 7,3,2 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the highest amount of each factor. 2 x 3 x 5 x 7 = 210, the LCM
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.
