HCF of 12 and 18
Define HCF.
Highest Common Factor (HCF), also known simply as the greatest common divisor or greatest common denominator, refers to the largest positive integer that divides two given integers without leaving any remainder.
What is LCM?
Least Common Multiple (LCM) of two integers is the smallest positive multiple that is divisible by both numbers.
What is the LCM of 12 and 18?
LCM of 12 and 18 is 36.
Is HCF(12, 18) greater than LCM(12, 18)?
As HCF(12, 18) = 6 and LCM(12, 18) = 36.
Thus, HCF (12, 18) is not greater than LCM(12, 18).
What is the Relationship between HCF and LCM?
For any two number x and y relationships between HCF and LCM is: HCF(x, y) × LCM(x, y) = xy.
How to Calculate HCF?
There are many methods to calculate HCF i.e.,
- Prime Factorization
- Listing Multiples
- Euclid’s Division Method
