GCF or HCF = Greatest Common Factor or Highest Common Factor
LCM= Lowest Common Multiple.
GCF : To understand GCF I illustrate an example. Suppose we need to calculate the GCF of two numbers of 16 and 18 , then first we write the factors of each number as tabulated below.
Numbers                     Factors 16 1 2 4 8 16
18 1 2

Unitary Method is that in which for further calculation value of unit (1) is required for further calculation.
Unit means one,  mathematically '1'.A, An or Per also mean '1'.
If we know the value of one then to find value of many we do MULTIPLICATION. Read this problem and the table.
Problem 1: Cost of one mango is $ 4. Find the cost of 8 mangoes.-
One Many 1 8 $ 4 ? Solution: 
As the Cost of 1 mango is $ 4. 
Therefor the cost of 8 mangoes is 8x4 = $ 32
Also Watch solution in the video given at the bottom .

If we know the value of many then to find value of one we do DIVISION. Read this problem.
Problem 2: Cost of one mango is $ 4. Find the cost of 8 mangoes.-
Many One 8 1 $ 40 ? Solution: 
As the Cost of 8 mango is $ 40. 
Therefor the cost of 1 mango is 40/8 = $ 5
Also Watch solution in the video given at the bottom .
If we know the value of many then to find value of many we first need to calculate the value of 1. 
Note:  students of lower classes faces more difficulties in this type of…

ACT 1 SCENE 1 [VENICE, A STREET]
1."Line 1 to 7 speech of Antonio" In truth I know not why Iam so sad.It makes me tired.But I still don't know how I have it,found it or came by it.What it is made up of and what os its origin.This sadness makes me so absent-minded that I do not know who Iam. 2.Line 8to 14speech of Salarino
You are stressed because you are worried about your rich ships (argosies ) which are sailing stately like gentlemen and important citizens on sea surface.Or as it is procesion of the sea to surpass the small commercial boats by these argosies.The small ships move up and down as if they were showing respect ,As if they speed fast by them with their canvas sailing.3.Line 15 to 22 speech of Salanio
Sir believe me If I had such a business operation the better part of my affection would be sailing at the sea.I should be holding up the grass blade to see in which direction the wind is blowing.I would be looking for ports , harbors and channels and every which w…
