Vedic Maths Trick to find the HCF of Algebraic Expressions
To appreciate the Vedic Maths process of finding the HCF you first need to know the other methods taught in school. I am giving you two other methods to compare with.
Example 1: Find the H.C.F. of x^2 + 5x + 4 and x^2 + 7x + 6.
While doing arithmetic calculations, we should normally check our calculation. But the checking should not be as tedious as the original problem. To solve this problem I am explaining below a very frequently used method which is discussed in Vedic Mathematics as well as by many other mathematicians.
Memory Trick: Halve the number you are multiplying by and place a zero after the number.
Example:
i. 5 × 136, half of 136 is 68, add a zero for an answer of 680.
ii. 5 × 874, half of 874 is 437; add a zero for an answer
Vedic Method of Multiplication: Base System of multiplication
Application: Multiplication of two numbers close to Hundred
Case 1: Both numbers greater than 100.
example of vedic multiplication using above method
• 103 x 104 = 10712
The answer is in two parts: 107 and 12,
107 is just 103 + 4 (or 104 + 3),
and 12 is just [...]
Short Cut for finding the cube of any two digit number is very easy using this method.
When any number has to be multiplied by a series of 9s, like 9, 99, 999, 9999 and so on than we can apply this very simple vedic maths technique to increase your speed of calculation.
Multiplying 5 Times an Odd Number: Subtract one from the number you are multiplying, then halve that number and place a 5 after the resulting number……
Divisibility Rules for 1 to 16, 24, 40, 80. Also includes simple divisibility rules for 7 and 13. We believe this is the most exhaustive set.
Divisibility by 2: If its unit’s digit is any of 0,2,4,6,8.
Ex : 100 is divisible by 2 while 101 is not…………
Special Vedic Maths Technique to multiply a number by 111
This post is to inform you about the origin of Vedic Maths from 16 Sutras and how Bharati Krsna Swamiji got the inspiration to find them out from our ancient Vedas
