Euclid Algorithm to find HCF
Euclid Algorithm to find HCF
Euclid Division Algorithm to Find HCF of More Than Two Numbers:
To find HCF of more than two numbers we will first apply Euclid Division Algorithm on two numbers and Hcf so obtained then grouped we the third number and so on.
Example: To find HCF of 12, 15 and 21
Solution: Find HCF of 12, 15
15= 12 X 1+ 3
12= 4 X 3 + 0
So HCF(15,12) is 3
Now, Find HCF of 3 and 21
21= 7 X 3 + 0
As remainder is zero
So HCF( 3, 21) = 3
Thus HCF of (12,15,21) = 3

My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.

10thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
