Prime numbers between the given numbers are 23 and 29
The prime factors of 20 are: 2 and 5.
23, 29 and 31 are the prime numbers in that range.
Any multiple of 20 includes the prime factors of 20.
The prime factors of 20 are 2, 2, and 5.
There are no common factors between these values since 11 is prime and 20 is composite. Then, there are no common prime factors between these values.

The GCF of 12 and 20 is 4.The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 20 are 1, 2, 4, 5, 10, and 20.The factors they have in common are 1, 2, and 4. Therefore, 4 is the greatest common factor.The greatest common factor can also be determined from the prime factors by multiplying the common prime factors together.The prime factors of 12 are 2, 2, and 3.The prime factors of 20 are 2, 2, and 5.The common prime factors are 2 and 2, so the greatest common factor is 2 x 2 = 4.The greatest common factor of 12 and 20 is 4
The factors of 20 are: 1, 2, 4, 5, 10, and 20.The prime factors of 20 are: 2 and 5.The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, and 36.The prime factors of 36 are: 2 and 3.
The factors of 12 are: 1, 2, 3, 4, 6, and 12.The prime factors of 12 are: 2 and 3.The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, and 42.The prime factors of 42 are: 2, 3, and 7.
To work this out, you need to write both numbers as their prime factors: 20 = 2x2x5 12 = 2x2x3 The next step is to identify any common prime factors. In this case both numbers have two 2s as prime factors. Multiply these together and you get 4. Therefore 4 is the HCF of 20 and 12.
The prime numbers between 20 and 30 are 23 and 29.
