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
No, 30 is not prime.
Use a factor tree. 30 15,2 5,3,2 2 x 3 x 5 = 30
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
'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'.
30 / \ 2 15 / / \ 1*2 5*3 2*5*3
8 is not a prime factor of 30. The prime factorization of 30 is 2x3x5.
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
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.
