HCF is also known as Highest Common Factor, GCF or GCD. HCF is the largest number that divides each of the given numbers without leaving a remainder.

The HCF formula can be expressed as,

**HCF Formula:**

HCF = (a × b)/ LCM(a,b)

where, a and b = Two terms

LCM(a, b) = Least common multiple of a and b
