Most times the question will specify "find the HCF" or "find the LCM." If you're trying to find common denominators, that's an LCM problem. If you're trying to reduce fractions, that's an HCF problem.

What is the lcm and hcf of 9 and 12?
lcm(9, 12) = 36; hcf(9, 12) = 3.
What is the LCM of 20 and 110?
To find the LCM of 110 and 20, you first need to break them up into their prime factors: 110 = 2x5x11 20 = 2x2x5 The next step is to identify the HCF. In this case the HCF will be 2x5 = 10. To find the LCM you multiply the numbers together and divide by the HCF: 110x20/10 = 220. Thus the LCM of 110 and 20 is 220.
Why is HCF important in maths?
It helps to reduce fractions.
What is the HCF and LCM of 100 and 120?
Write 100 and 120 in their prime compositions in power form: 100 = 223052 120 = 233151 For hcf, take lowest power of each prime across the compositions; for LCM, take highest powers: hcf = 223051 = 4 x 1 x 5 = 20 LCM = 233152 = 8 x 3 x 25 = 600
What do HCF and LCM stand for?
HCF means the highest common factor of two or more numbers. LCM means the lowest common multiple of two or more numbers.
What does LCM mean in maths terms?
it means lowest common multiple. the opposite to it is hcf or highest common factor ^_^

What is the HCF and LCM of 70 and 72?
The HCF is: 2The LCM is: 2,520
Can the HCF of two numbers be a factor of their LCM?
The HCF is always a factor of the LCM of two numbers. The HCF is a factor of both the numbers which are factors of their LCM. Thus the HCF is also a factor of the LCM of the two numbers.
What is the HCF and LCM of the numbers 526 and 213?
hcf: 1 lcm: 112,038

Can HCF and LCM of two numbers be 27 and 288?
No. The LCM MUST be a multiple of the HCF.
