Least Common Multiple (LCM) for 9 12 is 36.
LCM of 8 and 9 and 12 is 72.
HCF of 3 means the numbers both have a prime factor of 3. LCM of 12 means that, between the numbers, there are factors of 2, 2 and 3. But these 2s cannot be shared, else the HCF would be greater. Therefore, the numbers will need to be 3 and 2x2x3, or 12.
Least Common Multiple (LCM) for 6 9 12 is 36.
9
The GCF is 12.
The LCM is the product of the two numbers divided by their HCF. With 12 and 13, the HCF is 1. Therefore, the LCM will equal the product. With 12 and 14, the HCF is 2. Therefore, the LCM will be half of the product.
You cannot. The numbers 2 and 12 have hcf = 2 and LCM = 12 The numbers 4 and 6 also have hcf = 2 and LCM = 12 So if you just knew the hcf and LCM you would not know which of the two was the required pair.
if the product of two numbers is 810 if there hcf is 9 find Lcm
3 and 9.
The GCF is 3. The LCM is 120.
9= 3x3 12= 2x2x2x2x3 HCF = 3
Their HCF is 1 and their LCM is 36
3 and 12
2 and 12
2 and 12
None. But 4 and 6 have a LCM (not LMC) of 12 and HCF of 2.
