LCM is used to find the lowest common denominator in fractions
HCF is used to reduce fractions to their simplest terms
hcf = 42, lcm = 84.
The HCF is: 2The LCM is: 2,520
HCF - Highest Common Factor. LCM - Lowest Common Multiple.
The HCF helps when reducing fractions. The LCM helps when adding or subtracting fractions.
hcf(5, 15) = 5 lcm(5, 15) = 15.
For the division of quantities
The HCF helps in simplifying fractions and the LCM helps in finding the lowest common denominator in fractions
If you are a teacher who works with 27 pupils and 18 pupils and
to measure the tiles for our floor, if you need larger tiles so you could find by HCF and if smaller tiles you could find that by LCM
LCM is 20 and the hcf is 10
HCF = 3... LCM = 18 !
HCF is 48 and LCM is 576
HCF is 60 and the LCM is 360
hcf is 1 and LCM is 35
hcf = 42, lcm = 84.
They are: LCM = 120 and hcf = 8
The LCM is: 900The HCF is: 10
