2 x 2 x 5 = 20
No. Prime factors are the numbers that make up other numbers, but they have to be prime. Prime factorisation is the process of finding the prime numbers that create a number. This is when you multiply the prime numbers together and the product is the original number. For example: 20 5x4 5x2x2 This process is called prime factorisation. In this case, the prime numbers are 2, 2, and 5.
They are: 13+7 = 20
The question does not make sense since 20 and 30 are not prime numbers!
The prime factors of 20 are 2x2x5.
20 = 2 x 2 x 5
2 x 2 x 5 = 20
7 + 13 = 20 Note that there are no two prime numbers x and y that multiply to 20.

Prime factors of 20 are: 22 and 5 Prime factors of 250 are: 2 and 53 Multiply the highest prime numbers: 22*53 = 500 which is the LCM
2 x 2 x 5 = 20
These are the prime numbers 1-20 2,3,5,7,11,13,17,19
1200

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.
