Best Answer

An HCF of 1 means that the two numbers share no prime factors. An LCM of 30, means the numbers have between them prime factors of 2, 3 and 5. Thus any product combination of these factors will give a possible answer. You could have:

2 and 3x5 (15)

3 and 2x5 (10)

or

5 and 2x3 (6)

In order to have a LCM of 30, the two numbers must only have unique primes that multiply to give 30. 30 is the product of 2, 3 and 5. To have an HCF of 2, the two numbers must only share a factor of 2. Thus the factors of one must be 2 and 3, and the factors of the other must be 2 and 5:

2x3 = 6

2x5 = 10

Therefore the two numbers with an HCF of 2 and an LCM of 30 are 6 and 10.

or 2 and 30

How do you work out which 2 numbers have an lcm of 30 and an HCF of 3?

In these types of problems, the numbers can also be the answer. 3 and 30 have a GCF of 3 and an LCM of 30. Since the product of the GCF and LCM of two numbers is the same as the product of the numbers, you could also use another factor pair of 90, like 6 and 15.

3 and 9.


2 numbers have the LCM of 30 and an HCF of 3 what are the numbers?

HCF of 3 means that the two numbers share 3 as a prime factor. LCM of 30 means there is a 2, a 3 and a 5 as prime factors between the numbers. With this info, we can have the combination where one number has a 2 and the other a 5 (and both have the 3) or one number has just the 3 and the other has 2, 3 and 5. Thus the 2 numbers can be 6 and 15. Or they can be 3 and 30.
