Yes, 2x3x5 is a prime factorization because it has prime numbers multiplied to give a number. It is the prime factorization of 30.
The prime numbers are 2x15x3x5. That is what i think if not i could ask my teacherBy Safaa Khattab(Repeated answer removed)The prime factors are 2x3x5=30
30
30=2x3x5
2x3x5
It is 30
2x3x5
2x3x5
Prime factor both numbers and use all the factors that are in both numbers. 30=2x3x5 180=2x2x3x3x5 2x3x5=30 is the gcf

8 is not a prime factor of 30. The prime factorization of 30 is 2x3x5.
If by "least number" you mean "smallest positive integer", then the answer is the product of the three smallest primes: 2x3x5 = 30
To find the HCF of 20 and 30, break them down into their prime factors: 20 = 2x2x5 30 = 2x3x5 The next step is to identify any common prime factors. In this case both numbers have a 2 and a 5 as prime factors. Multiply these together and you get: 2x5 = 10 Therefore the HCF of 20 and 30 is 10.
