2 x 3 x 5 = 30
30/2 = 15/3 = 5/5 = 1 2 x 3 x 5 = 30
the prime factorizatation of 30 is 30 ^ 10x3 ^ 5x2 =5x2x3

Yes.
*)1 5)5 3)15 2)30 The prime factorization of 30 is 2 x 3 x 5.
The prime factors of 30 are: 2 + 3 + 5 = 10
The prime factorization of 560 is: 2, 5, and 7
The prime factorization of 30 is 2 * 3 * 5Start with the lowest prime number that will divide into the given number evenly.The result will be one of the prime factors and a number that might need to be factored. In the case of 30, 2 is a prime number and 15 needs to be factored further.The lowest number that will divide into 15 evenly is 3. 3 * 5 equals 15. 5 is also a prime number, so the prime factorization of 30 is 2 * 3 * 5.To find the prime factors of any number then divide the number by prime numbers of increasing value. When a prime number wholly divides the original number repeat the process with the same prime number but each time with the new quotient until complete division does not occur. Repeat with a prime number of higher value until the final quotient is 1.30 ÷ 2 = 1515 ÷ 2 complete division does not occur15 ÷ 3 = 55 ÷ 3 complete division does not occur5 ÷ 5 = 1 : quotient = 1, prime factorization is completeThe prime factors are therefore 2, 3 and 5.2 x 3 x 5 = 30

Add them up. The prime factors of 30 are 2, 3 and 5. You can handle the rest.
The question does not make sense since 20 and 30 are not prime numbers!
To find the Least Common Multiple (LCM) of 15 and 30, we first need to find the prime factorization of each number. The prime factorization of 15 is 3 x 5, and the prime factorization of 30 is 2 x 3 x 5. To find the LCM, we take the highest power of each prime factor that appears in either number, which gives us 2 x 3 x 5 = 30. Therefore, the LCM of 15 and 30 is 30.
