Finding the H.C.F. of more than two numbers:
For example we have to Find the H.C.F. of three numbers (a, b, c)
H.C.F. of [(H.C.F. of any two i.e. a, b ) and (the third number c)] gives the H.C.F. of (a, b, c) numbers.
H.C.F. of (a, b, c) = H.C.F [ H.C.F (a, b) , c]
Above formula is applicable for list of more than 3 numbers also, please check below formula for 4 numbers A, B, C, D
H.C.F. of (A, B, C, D) = H.C.F [ H.C.F [ H.C.F (A, B) , C] , D]
Use following calculator for getting Highest Common Factor (H.C.F.) or Greatest Common Measure (G.C.M.) or Greatest Common Divisor (G.C.D.) of numbers.
