LCM and HCF Formula and Tricks

HCF & LCM OF NUMBERS

H.C.F: It Stands for Highest Common Factor / Greatest Common Divisor (G.C.D) and Greatest Common Measure (G.C.M).

L.C.M : It Stands for Lowest Common Factor / Lowest Common Divisor (L.C.D) and Lowest Common Measure (L.C.M).

The H.C.F. of two or more numbers is the greatest number that divides each one of them exactly.

The least number which is exactly divisible by each one of the given numbers is called their L.C.M.

Two numbers are said to be co-prime if their H.C.F. is 1.

H.C.F. of fractions = H.C.F. of numerators/L.C.M of denominators

L.C.M. of fractions = G.C.D. of numerators/H.C.F of denominators

Product of two numbers = Product of their H.C.F. and L.C.M.
