NUMBERS: IMPORTANT FACTS AND FORMULAINMPORTANT FACTS AND FORMULA

I. Factors and Multiples : If a
number x divides another number y exactly, then, we say that x

is
a factor of y. In this case, y is called a multiple of x.

II. Highest Common Factor (H.C.F.) or Greatest Common Measure
(G.C.M.) or

Greatest Common Divisor (G.C.D.): The H.C.F. of two or more than two numbers is

the
greatest number that divides each of them exactly.

There
are two methods of finding the H.C.F. of a given set of numbers:-

1. Factorization Method:- In this
method, we express each one of the given numbers as the product of prime
factors. The product of least powers of common prime factors gives H.C.F. Read more,,,,,,,,,
